Founded1984

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.
