A guide to the leading public relations agencies in Philadelphia — legacy independents with national rosters, mid-size integrated shops, women-owned boutiques, and crisis specialists. Each firm below is profiled in depth on Everything-PR; this hub is the index.
Brownstein Group
Brownstein Group is one of the oldest privately held communications firms in Philadelphia. Founded in 1964 by Benny Brownstein as an advertising agency, the firm grew into a full-service brand, advertising, public relations, social, and digital shop. Marc Brownstein, Benny's son, serves as CEO. The agency runs roughly 70 staff and is a past Ad Age "Best Place to Work" honoree and PRSA Silver Anvil winner.
Client roster includes eBay, IKEA, Comcast, ESPN, and Western Union, alongside ongoing pro bono work for non-profits. Brownstein's positioning is built on the combination of advertising heritage and modern PR — brand strategy, advertising, public relations, social media, digital, and B2B all under one roof.
Buchanan Public Relations is a Philadelphia-based full-service public relations, digital strategy, and crisis communications agency founded in 1998 by Anne A. Buchanan, APR. Ranked #126 on O'Dwyer's Top PR Firms list and a founding member of the Public Relations Global Network (PRGN), the consortium of 50+ independently-owned firms worldwide.
In September 2025 the firm completed an internal ownership transition: 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: financial services, insurance, healthcare, consumer goods, professional services, and non-profits.
