Trevelino/Keller is one of the largest independent integrated communications agencies headquartered in the United States Southeast. Founded in Atlanta in 2003 by Dean Trevelino and Genna Keller, the firm has built a national reputation across 12 industry segments and operates as an integrated public-relations, growth-marketing, and creative shop measured against outcome-driven business goals rather than media impressions. Dean Trevelino and Genna Keller serve as Co-Chief Executive Officers. In July 2024, the firm completed the acquisition of Marsden Marketing, a nationally ranked growth-marketing firm — a transaction that was a finalist for the Atlanta Business Chronicle and ACG Atlanta 2025 Deal of the Year.
The Founders and the Founding Era
Dean Trevelino and Genna Keller met inside the holding-company communications system before founding Trevelino/Keller in Atlanta in 2003. Both came from Shandwick International (now part of Weber Shandwick), the Weber Group, and Ogilvy & Mather. The founding thesis was that the integrated brief — public relations, growth marketing, and creative under one roof — would outperform single-discipline shops for the founder-led and middle-market growth companies that drive the Southeastern United States economy. The thesis held. The firm has spent two decades building inside that market and now operates nationally.
The 2024 Marsden Marketing Acquisition
In July 2024, Trevelino/Keller acquired Marsden Marketing as part of a dual strategy: expand the firm's growth-marketing practice and elevate the positioning as a fully integrated agency. The deal added HubSpot Platinum Partner status and significantly expanded the firm's customer-relationship-management and marketing-technology capabilities. The transaction was named a finalist for the Atlanta Business Chronicle and ACG Atlanta 2025 Deal of the Year. The acquisition is the largest in the firm's history.
The Atlas Alliance and the Start-Up Council
In 2005, Trevelino and Keller founded the Atlas Alliance, a federation of independent boutique communications agencies operating across the United States, United Kingdom, United Arab Emirates, Singapore, and Atlanta — providing a global delivery capability without the holding-company overhead. In 2006, the firm launched the Start-Up Council, a pro-bono program supporting early-stage companies with strategic counseling, media and investor introductions, and access to the founders' broader community network. Both programs have continued under Co-CEO leadership.
The Roster
The firm's client experience includes Nathan's Hot Dogs, Paris Baguette Boulangerie, Verizon Wireless, the College Football Hall of Fame, Paymetric, SOC Telemed, UnitedHealthcare, Kreate, and Bluebox Smart Ice and Water, among a broader book that spans the firm's twelve industry segments. The integrated-agency model means accounts typically operate across PR, growth marketing, and creative simultaneously.
Service Offering
The firm operates three integrated capability arms. The Public Relations practice spans media relations, corporate communications, executive positioning, content, and analyst relations. The Growth Marketing practice runs as a HubSpot Platinum Partner with full in-house customer-relationship-management, marketing-automation, and demand-generation execution. The Creative Studios deliver brand identity, web, design, and broadcast production — approaching 200 total agency awards, including four Hermes Creative Awards in 2024 (three Platinum, one Gold).
Position in the Category
Trevelino/Keller sits at the top of the Atlanta independent integrated-communications category, with national positioning across 12 industry segments: technology, healthcare, financial services, transportation, manufacturing, energy, franchising, food and beverage, lifestyle and consumer products, professional services, sports marketing, and hospitality. In Atlanta specifically, the firm ranks first or second in nearly every segment it competes in. The peer set across the Southeast includes Jackson Spalding, RBB Communications, Carmichael Lynch Relate (Minneapolis with Atlanta presence), and the Atlanta offices of major holding-company networks. Trevelino/Keller differentiates on the integrated model, the HubSpot Platinum Partner status, and the 2024 Marsden acquisition.
