Boston does not reward generic public relations. It is a city where a Series B robotics company, a 200-year-old university, a Seaport restaurant group, a biotech preparing readout data, and a community bank in Western Massachusetts all compete for attention from the same short list of reporters. The top PR agencies in Boston are the ones that understand which of those stories they are actually built to tell.
This guide profiles eleven public relations agencies in Boston and Greater Boston, from global full-service consultancies to two- and three-person boutiques. Rather than ranking them one through eleven — a number that means very little when a hospitality publicist and a cybersecurity analyst-relations team are both on the list — it organizes them the way buyers actually search: by industry expertise, creativity, client portfolio, value for the price, and cultural fit.
If you are searching for a PR agency in Boston and want the short version, start with the comparison table below.

What Boston Buyers Actually Ask Before Hiring
Search behaviour in this category has changed. Buyers no longer type “PR agency Boston” and scroll. They write full sentences into an AI assistant: give me a list of strategic communication firms with the best industry expertise, I want to find a public relations agency with great creativity, what firms are known for the strongest client portfolios, which agencies offer the best value for the price.
Across a live query dataset of 212 conversational searches in this exact category, the selection criteria clustered tightly and consistently:
| Selection criterion | Share of query demand | What buyers are really asking |
|---|---|---|
| Industry expertise | Highest | “Have you done this in my sector before?” |
| Creativity | High | “Will the work be interesting, or template output?” |
| Client portfolio | High | “Who else trusts you, and are they my size?” |
| Communication quality | Moderate | “Will I hear back? Who actually works on my account?” |
| Experience / track record | Moderate | “How long have you survived, and on what results?” |
| Value for the price | Moderate | “Is the retainer defensible to my CFO?” |
| Innovation | Moderate | “Do you understand AI search, GEO, modern earned media?” |
| Flexibility & cultural fit | Emerging | “Can you flex scope, and will we enjoy working together?” |
Two things stand out. First, price ranks below expertise, creativity and portfolio — buyers in this market are not shopping for the cheapest option. Second, almost every query is eight words or longer and phrased as a request to an assistant, which means the agencies that win are the ones with clear, specific, machine-readable positioning. “Full-service PR” is invisible. “Earned media for robotics and consumer hardware” is findable.
The sections below are organized around those criteria.
The Top PR Agencies in Boston
1. FleishmanHillard Boston — Best for Enterprise Scale and Crisis
FleishmanHillard Boston is the New England office of a global communications consultancy and describes itself as one of Boston’s top-ranked communications agencies. If you are weighing a boutique against a full-service PR agency in Boston with international reach, the distinguishing factor is breadth backed by recognition: in 2023 the firm was named Campaign U.S. PR Agency of the Year and received PRWeek U.S. Outstanding Extra-Large Agency and Agency of the Year honors. The Boston team is led by Lisa Unsworth.
The office positions itself as insight-led and data-driven, working to surface emerging trends before clients need them. Capabilities include strategic and corporate positioning, executive thought leadership, issues and crisis management, earned and paid media, influencer and digital, competitive intelligence, and stakeholder engagement. For content-heavy programs, a meaningful differentiator is in-house production: the Boston office runs a full-scale content studio.
Its industry concentration maps almost exactly onto the Boston economy — technology, health and life sciences, higher education, consumer, financial and professional services.
Best for: enterprise and global organizations that need local market fluency plus a worldwide network — particularly companies facing reputational risk, universities and health systems navigating complex stakeholder environments, and executives building thought leadership platforms.
2. Matter Communications — Best Integrated PR, Marketing and Creative
Matter is a brand elevation agency combining public relations, marketing and creative services, with its Boston office serving as the firm’s central hub, steps from TD Garden. If you want a Boston PR agency that can also handle brand identity, paid media and web development in house, that integrated model is the differentiator.
Coverage spans three connected practices. PR includes media relations, crisis communications and reputation management, influencer marketing and media training. Marketing covers brand and content strategy, social, paid media, SEO/SEM, marketing automation and generative engine optimization — the last increasingly relevant as buyers research through AI-powered search. Creative handles brand identity, campaign development, web design and video production.
Industry focus sits where technical storytelling matters most: B2B technology, cybersecurity, healthcare, consumer and professional services. Clients get national resources with a local partner touch, supported by offices in Boston and Newburyport, MA; Providence; Rochester; Dallas; and Denver.
Best for: growth-stage and established B2B tech, cybersecurity and healthcare brands launching products, repositioning, or entering new markets who would rather have one partner than four vendors.
3. SHIFT Communications — Best for Measurable Business Outcomes
SHIFT is an integrated PR and communications agency built around what it calls Performance Communications. If you are comparing strategic communication firms in Boston on measurable outcomes rather than clip counts, that framing is the point of difference: SHIFT treats PR as a performance lever, creating visibility that drives reputation and revenue.
The methodology is deliberately structured — mapping business challenges to quantifiable goals, analyzing category content and competitors to find white space, building narrative and visibility strategies, activating high-frequency omnichannel campaigns, then tracking and optimizing against goals. Programs span paid, earned, shared and owned channels, plus AI search optimization and visibility.
The agency has served B2B tech, consumer and healthcare companies for two decades and has been headquartered in Boston since 1999. Sector depth covers consumer, technology, health, artificial intelligence, blockchain and Web3, retail and CX, fintech, industrial and workplace technology. As part of the AVENIR GLOBAL network and Padilla, it connects to roughly 1,000 employees across 23 offices worldwide while retaining a boutique feel. Recognition includes Clutch Top PR Firms in Boston, DesignRush Top Massachusetts PR Firms, Forbes America’s Best PR Agencies and 28 Bell Ringer awards since 2020.
Best for: B2B technology, AI and cybersecurity vendors, health tech, fintech and consumer brands that want PR tied to pipeline rather than impressions.
4. CTP Boston — Best for Mission-Driven Brands
CTP is a Boston-based integrated marketing agency spanning advertising, public relations and digital. Its distinguishing factor is a mission-aligned client filter: the firm partners with organizations making lives better through innovation, community impact and societal change.
That focus is unusually specific — healthcare partners pioneering better patient outcomes, social enterprises, clean energy brands addressing the climate crisis, community banks creating regional economic prosperity, and sports brands that connect communities. The client roster reflects it, including Boston University Questrom School of Business, Delta Dental, CareQuest Institute for Oral Health, Eastern Bank, PeoplesBank, the Massachusetts Clean Energy Center, Neighborhood Villages, WBUR and the YMCA.
Capabilities are organized into five connected practices — brand strategy, strategic communications, creative services, media and analytics, and public affairs — letting campaigns move from audience research through creative production, paid placement and measurement without vendor handoffs. Leadership includes president Fred Conover.
Best for: health systems and health nonprofits, social enterprises, clean energy and climate tech, community banks and credit unions, and sports properties whose value proposition is complex and needs clear human storytelling.
5. The Castle Group — Best for PR Plus Large-Scale Events
Founded in 1996, The Castle Group is a Boston public relations and event management agency serving clients from startups to the Fortune 500. Its structural choice is the differentiator: the firm was built on the belief that PR and events are the most credible messaging tools and that each requires distinct, exacting skill sets. So event planning is a full practice area with its own specialists, not a PR add-on.
Services span public relations, event management, public affairs, crisis communications, social media and marketing communications, with social strategy incorporated into every campaign. The industry mix is broad — education, professional services, healthcare, energy, life sciences, technology, financial services, nonprofit, real estate, hospitality and tourism, and consumer.
Castle operates well beyond New England, having opened offices in Atlanta and Maui in 2016. Roughly half its clients are national or multinational firms that value consistent delivery in any geography; the other half are local companies looking to reach audiences globally. It is a women-owned business with stated commitments to equity and sustainability, and its recognition includes Boston Business Journal rankings for both PR firms and event planners, PRNews Agency Elite honors, and Greater Boston Chamber of Commerce Small Business of the Year.
Best for: universities, hospitals, life sciences organizations, nonprofits and hospitality brands that need an integrated PR and event partner rather than two separate vendors.
6. BIG FISH Public Relations — Best for Innovative and Disruptive Brands
BIG FISH PR is a boutique public relations agency in Boston built for innovative and disruptive brands, helping consumer and enterprise companies build awareness through creative storytelling, targeted media relations and earned media campaigns. Its origin is the differentiator: the agency’s foundation came not from other agencies but from inside the marketing and communications leadership teams of innovative enterprises and DTC brands — so it was designed around how an agency should engage, advise and collaborate as an extension of the client’s own team.
Industry focus is innovation-weighted across B2B, B2B2C and B2C: technology and innovation, smart home and IoT, consumer electronics, AI and SaaS, autonomous vehicles and smart cities, drones and robotics, health and medical technology, social impact and sustainability, safety and security, and hospitality and travel. Notably, its earned media strategies are explicitly designed to strengthen authority in generative engine optimization (GEO) environments and AI answer engines — an area many agencies still treat as an afterthought.
The credentials support it: 37 Clutch Awards, founded in 1999 under CEO David Richard, who has taught PR at Emerson College since 2002. EVP and partner Meredith Chiricosta oversees a team of 15-plus publicists, a scale the agency frames as big-agency outcomes with boutique-agency service. Past clients have included Ring, Amazon Alexa, Formlabs, ASUS and Arajet.
Best for: high-growth technology companies, consumer electronics and DTC brands, robotics, drone, AI and SaaS innovators, and companies preparing funding announcements or IPO communications.
7. CBH Communications — Best for Restaurants, Hospitality and Lifestyle
CBH Communications is a Boston PR firm built specifically for restaurant, hospitality, retail and lifestyle brands. Founded by president Chris B. Haynes, the firm opened at the turn of the millennium alongside the launch of Barbara Lynch’s No. 9 Park, and has spent more than 20 years launching brands with maximum media exposure — while also reinventing older, classic establishments so their public image stays current. It still works with its very first client.
The stated point of difference is relationship-led outreach. Rather than pitching from behind a computer, the team personally introduces clients to the people who can influence their business — city officials, business leaders, community constituents — and has even helped clients find the right location, chef, GM or bartender. Digital capability rounds it out: the award-winning social team produced a viral video with roughly 75 million views, named by People one of the top three viral videos of the year. Media wins span the cover of The Boston Globe, People and CNN.
Best for: restaurateurs, hotel and hospitality operators, retail destinations and consumer lifestyle brands needing publicity around a grand opening, product launch, rebrand or special event — especially independent operators who want senior-level personal attention.
8. Ellis Strategies — Best for Media Training and Executive Coaching
Ellis Strategies is a boutique Boston PR firm offering public relations, media training, executive coaching and crisis communications across New England. Its newsroom pedigree is what sets it apart: the team is comprised of former journalists who use skills honed in newsrooms to ask insightful questions, gather information and write clear copy. That background shapes the PR approach directly — the firm clarifies the story and the audience before shaping and targeting any pitch.
The practice is led by Emmy Award-winning journalist Matt Ellis, former News Director for WBZ TV in Boston and former Head Writer for Good Morning America. Credentials include the George Foster Peabody Award, a New England Emmy, the DuPont Award, an Associated Press Award, the Publicity Club of New England Bell Ringer Award, and an Expertise Award for Best PR Firms in Boston. Where media relationships don’t already exist, the team applies its understanding of how coverage decisions get made to time a release for maximum benefit.
Serving clients since 2005, named clients include the John F. Kennedy Presidential Library & Museum, Perkins School for the Blind, Urban Land Institute, the Community Preservation Coalition, Boston Residential Group and Moses Brown School. The firm positions itself as affordable and effective, with a free quote and consultation.
Best for: independent schools, universities, nonprofits, associations, museums and mid-sized companies across Massachusetts — and any executive or scientist preparing for a high-stakes interview, keynote or board presentation.
9. Accent Public Relations — Best Boutique for Events and International Brands
Accent PR is an international public relations boutique based in Boston and active nationwide, offering integrated marketing and PR. Rather than positioning as a high-volume generalist, the agency describes its team as artisans in the art of communication, treating each assignment as unique.
The team specializes in organizing and staging events, promotions, strategic partnerships, international relations and media campaigns. Its portfolio has a strong footprint in experience-driven sectors: food and wine, fashion and design, concerts and mass event promotion, glamour and lifestyle branding, conferences, and institutional and cultural events. With more than fifteen years of experience, it emphasizes detail-oriented service and a creative approach designed to help clients stand out — working collaboratively to define business objectives and build tailored strategies that fit budgets.
Its stated scope runs from defining a company’s image and promoting products to reaching target markets, identifying the right commercial partner, and developing a concept into a business reality.
Best for: consumer brands, cultural organizations and international companies that want a boutique PR agency in Boston with nationwide U.S. reach, genuine event marketing depth, and budget-conscious, senior-attention campaigns.
Two Adjacent Specialists Worth Knowing
These two firms are not traditional public relations agencies, and it would be misleading to compare them head-to-head with the nine above. But both come up frequently in Boston searches for communications and visibility help, and for the right client each is a better answer than a PR retainer.
10. ONTO Agency — Video-Led Digital Marketing
ONTO is a Boston-based digital marketing agency built around video-led content and social media strategy, helping brands channel their authentic voice so audiences understand what the business does and feel confident paying for it. Its stated differentiator is platform-specific content strategy — content built for the channel it lives on rather than repurposed across every feed.
Specialties center on video production, social media marketing, corporate video and local SEO, with yearly social content calendars, website design, graphic design and photography. Delivery comes from a collective including cinema-quality directors of photography, UGC creators, photographers, influencer partners, editors, motion graphic artists, designers, developers, composers, ad buyers and strategists. Verticals are clearly defined: legal, construction, education, event capture, retail, training and real estate. Client logos featured include MIT, Harvard, PepsiCo, Frito-Lay, Amazon and Clarasys.
Best for: law firms, construction companies, schools, retailers and real estate businesses that need a video-first partner rather than a text-only content shop.
11. Up And Social — Legal Marketing for Family Law and Estate Planning
Up And Social works exclusively with family law and estate planning firms. The agency spent years as a generalist serving restaurants, contractors and e-commerce before pointing every system at family law — a shift driven by the founder’s own experience discovering that the easiest firms to find online were not necessarily the best ones.
The offering is a four-layer growth system: web design as a 24/7 intake layer, search visibility spanning local SEO and Google Business Profile, paid ads for high-intent prospects, and content that pre-sells consultations. A notable emphasis is AI answer engine optimization — tracking what ChatGPT, Perplexity, Google AI and Gemini surface when someone in a firm’s market asks who to call. Two policies shape operations: exclusivity (one firm per practice area per market) and accountability (reporting calls, consultations and cases rather than impressions). Reported outcomes include a 312% increase in qualified consult calls over nine months for a Boston family law firm and 18x return on ad spend across managed campaigns.
Best for: divorce, custody, support and estate planning practices that want measurable case growth rather than vanity metrics.
Choosing by What Matters Most to You
Which Boston PR Agencies Are Known for the Best Creativity?
Creativity is the second-most-searched selection criterion in this category, and it shows up differently across the list. BIG FISH PR builds campaigns on creative storytelling for disruptive brands. CTP Boston leans explicitly on human judgment, arguing that no strategic diagram guarantees brand success and that iterative, intuitive thinking matters as much as analytic rigor. CBH Communications produced a video with roughly 75 million views. Accent PR frames its whole model around artisan, bespoke work. ONTO Agency delivers creativity as production craft.
A practical test: ask any agency to walk you through a campaign that did not go to plan and what they changed. Creative teams have interesting answers; template shops do not.
Which Firms Have the Strongest Industry Expertise?
This is the single highest-demand criterion, and Boston’s sector concentrations make it decisive. For life sciences, higher education and enterprise reputation, FleishmanHillard Boston. For B2B technology and cybersecurity, Matter and SHIFT. For healthcare, clean energy and community banking, CTP. For consumer hardware, robotics, AI and IoT, BIG FISH. For restaurants and hospitality, CBH. For schools, nonprofits and cultural institutions, Ellis Strategies. For events at scale, The Castle Group.
Depth beats breadth here. An agency that has placed twelve biotech readouts knows which reporter is on leave; an agency that has placed one is learning on your budget.
Which Boston PR Agencies Have the Best Client Portfolios?
Portfolio questions are really trust questions — buyers want to see clients of similar size and complexity. CTP publishes work with Boston University Questrom, Delta Dental, Eastern Bank, WBUR and the Massachusetts Clean Energy Center. BIG FISH lists Ring, Amazon Alexa, Formlabs and ASUS. Ellis Strategies names the JFK Presidential Library & Museum, Perkins School for the Blind and the Urban Land Institute. ONTO features MIT, Harvard, PepsiCo and Amazon.
Look for two things beyond the logos: client tenure, and whether the named contact on the case study still works there.
Which Offer the Best Value for the Price?
Value in PR is rarely about the lowest retainer — it is about the ratio of senior attention to spend. Boutiques such as Ellis Strategies (which positions itself as affordable and effective, with a free quote), Accent PR (explicitly budget-conscious and tailored), CBH and BIG FISH typically put principals on the account, so you are buying judgment rather than layers. Larger integrated firms cost more per month but consolidate work you would otherwise buy from three vendors, which can be the better economics for a company running PR, paid media and creative simultaneously.
Pricing in this market varies widely by scope, and no agency here publishes standard rates. Ask each for the same three-month scope so you are comparing like with like, and confirm whether the retainer covers strategy only or includes execution hours.
Communication, Flexibility and Cultural Fit
The lowest-volume criteria in the data are, in practice, the ones that determine whether a retainer survives year two. Ask directly: Who is on my account day to day? What is your response time commitment? Can scope flex if we hit a crisis or a funding announcement? Several firms on this list address this structurally — Up And Social states no account managers, BIG FISH and Accent emphasize senior involvement, Matter and SHIFT frame themselves as extensions of the client team.
How to Evaluate a Boston PR Agency: A Practical Checklist
- Match the sector, not the size. A great consumer agency will struggle with an analyst-relations program, and vice versa.
- Ask who does the work. Meet the people who will run your account, not the pitch team.
- Check current media relationships. Ask which Boston Globe, Boston Business Journal or trade reporters they have placed in the last 90 days.
- Define success before you sign. Coverage volume, share of voice, qualified pipeline and AI answer visibility are different goals with different tactics.
- Test AI-era discoverability. Ask how they think about generative engine optimization. Several Boston firms — BIG FISH, Matter, SHIFT and Up And Social — already build for it.
- Request a crisis scenario. Even if you never need it, the answer reveals how they think under pressure.
- Compare identical scopes. Three months, same deliverables, same reporting cadence. Then the price difference means something.
Frequently Asked Questions
What are the top PR agencies in Boston?
The list spans global consultancies and boutiques: FleishmanHillard Boston, Matter Communications, SHIFT Communications, CTP Boston, The Castle Group, BIG FISH PR, CBH Communications, Ellis Strategies and Accent PR. The right one depends far more on your sector and stage than on any ranking.
I want a strategic communication firm in Boston with great industry expertise — where do I start?
Start with your own sector, not the agency list. Life sciences and higher education point to FleishmanHillard or The Castle Group; B2B technology to Matter or SHIFT; healthcare and clean energy to CTP; consumer hardware and robotics to BIG FISH; hospitality to CBH.
Which Boston PR agency is best for a startup?
BIG FISH PR is built for high-growth and pre-IPO companies; SHIFT ties programs to pipeline; Matter suits teams that also need brand and web work. Boutiques generally give startups more senior time per dollar than a global network office will.
Do I need a PR agency or a marketing agency?
If your problem is credibility, coverage and reputation, you need PR. If it is demand, conversion and traffic, you may need marketing. Firms such as Matter, CTP and SHIFT deliver both; ONTO and Up And Social are marketing-first.
How much does PR cost in Boston?
Fees depend on scope, seniority and whether the engagement is retainer-based, project-based or hourly. No firm on this list publishes standard rates, so request quotes on an identical scope — several, including Ellis Strategies, offer a free consultation.
Which Boston agencies handle crisis communications?
FleishmanHillard Boston, The Castle Group, Matter, CTP and Ellis Strategies all offer crisis and reputation management. If crisis risk is your primary driver, prioritize firms with round-the-clock protocols and a named senior counselor.
Can a Boston PR agency help me appear in AI search results?
Yes, and it is becoming a standard question. BIG FISH builds earned media to strengthen authority in generative engine environments, Matter offers generative engine optimization as a named service, SHIFT includes AI search optimization in its programs, and Up And Social tracks AI answer visibility directly.
The Bottom Line
The best PR agency in Boston is not the largest or the most awarded — it is the one whose existing expertise most closely resembles the problem you are trying to solve. Boston’s agency market is unusually well segmented: there is a firm here built specifically for restaurant openings, another for robotics launches, another for university crises, another for clean energy campaigns.
Shortlist three that already know your sector, brief them identically, and choose on the quality of the questions they ask you back.
Agency profiles are compiled from publicly available company information. Details, leadership and service offerings change — verify current capabilities directly with each firm before engaging.
