Philadelphia is a distinctive PR market, anchored by Comcast, Vanguard, Penn Medicine and the broader Delaware Valley healthcare and financial-services economy. The city has one of the deepest concentrations of long-running independent PR firms of any U.S. metro, alongside a mid-Atlantic public-affairs bench and a substantial nonprofit and institutional communications tier. Most firms below have their own Everything-PR profile, and this page is the index.

Which PR firms lead in Philadelphia?

Five firms lead Philadelphia PR, and each anchors a different tier of the market. Brownstein anchors integrated brand and PR, Buchanan anchors independent full-service work, Braithwaite anchors crisis communications for legal teams, Maven anchors real estate and A/E/C, and Philly PR Girl anchors events and nonprofit work.

Brownstein Group

Brownstein Group is one of Philadelphia's longest-running independent marketing firms. It was founded in 1964 by the father of current CEO Marc Brownstein as an advertising agency, and it has since grown into a network of four specialty agencies: Born and Raised for advertising, Red Thread PR, Nucleus Digital and Studio215.

The network rebranded its advertising arm as Born and Raised, a move Marc Brownstein tied to the firm's 61-year history. Brownstein was a finalist in Adweek's 2023 Agency of the Year program in the small agency category, and past clients include eBay, IKEA, Comcast, ESPN and Western Union. Red Thread PR, the PR specialty shop, works with mission-led organizations and has named Sharing Excess among its clients.

Buchanan Public Relations

Buchanan Public Relations is a Philadelphia full-service public relations, digital strategy and crisis communications agency, founded in 1998 by Anne A. Buchanan, APR. It is a founding member of the Public Relations Global Network (PRGN), a consortium of more than 50 independently owned firms worldwide, and was ranked #126 on O'Dwyer's list of top PR firms in 2025. EPR's reader's guide to the O'Dwyer's rankings explains how buyers should read that placement.

In September 2025 longtime partners Megan Yocum and John Reynolds, minority owners since 2023, acquired the remaining interests from founder Anne Buchanan and now serve jointly as principals. The handoff kept the firm independent and Philadelphia-headquartered. Specialties include financial services, insurance, healthcare, consumer goods, professional services and nonprofits.

What is changing in the Philadelphia PR market?

Three shifts define the Philadelphia PR market in 2026: ownership changes at long-running firms, specialty networks replacing single agencies, and healthcare and higher education driving demand. Each affects how a buyer should vet a firm.

• Ownership is moving. Buchanan passed to its principals in September 2025 and Braithwaite announced its move to Arketi Group in May 2026, so check who owns a firm before signing.
• Networks are replacing single agencies. Brownstein Group now sells advertising, PR, digital and creative through four separate shops.
• Healthcare and higher education drive demand. Penn Medicine, CHOP, Jefferson Health, Temple Health and the Delaware Valley university system generate the most sustained PR work in the market.
