Cline Davis & Mann (CDM) was a highly influential and pioneering advertising agency specializing in the healthcare and pharmaceutical industries. Founded in 1984 by Morgan Cline, Clyde Davis, and Fred Mann, the agency quickly established itself as a leader in direct-to-physician and direct-to-consumer (DTC) advertising. Known for its creative and strategic approach, CDM developed numerous award-winning campaigns for major pharmaceutical brands. In August 2000, Cline Davis & Mann was acquired by Omnicom Group, a global leader in marketing communications. It subsequently became a cornerstone of Omnicom Health Group (OHG), continuing its legacy of excellence in healthcare communications under various OHG agency brands. While the standalone Cline Davis & Mann brand has evolved and integrated into the broader OHG network (like TBWA\WorldHealth and DDB Health), its impact on healthcare advertising remains significant.
The New York headquarters served as the central hub for all agency operations, including client services, creative development, strategic planning, media, and administrative functions for its global healthcare advertising campaigns.
As a prominent advertising agency, its offices were likely designed to foster creativity and collaboration, featuring open-plan areas, brainstorming rooms, and presentation suites. Specific architectural details of former locations are not widely publicized.
The work culture at Cline Davis & Mann was known for being dynamic, innovative, and demanding, typical of a leading advertising agency. It emphasized creativity, strategic thinking, and a deep understanding of the pharmaceutical and healthcare markets. Post-acquisition, this culture influenced the development of Omnicom Health Group's agencies.
The New York headquarters was significant as the birthplace of many groundbreaking healthcare advertising campaigns that shaped the industry. It was the nerve center for a company that played a pivotal role in the evolution of pharmaceutical marketing.
While Cline Davis & Mann as a standalone entity was primarily US-based with some international reach, its acquisition by Omnicom Group significantly expanded its global footprint. Today, its legacy functions are supported globally through the extensive network of Omnicom Health Group agencies. These agencies provide a full spectrum of healthcare communications services, including pharmaceutical advertising, medical education, digital marketing, public relations, and market access strategies across North America, Europe, Asia-Pacific, Latin America, and other key international markets.
Historically, a key address was 488 Madison Avenue (though this may have changed over time and post-acquisition). As part of Omnicom Health Group, operations are now within OHG's global network.
