Marketing Design Group occupies Fifth Avenue in downtown San Diego's Bankers Hill district, operating as mdg, a Freeman company, since its founding in 1976. Full-service trade show and association campaigns integrate attendee acquisition, exhibitor recruitment, and on-site production logistics, including food-and-beverage coordination through catering partners like Urban Kitchen Catering for client event programming. Headquartered in San Diego with offices in Washington, D.C. and Alexandria, Virginia, the agency specializes exclusively in event and association marketing rather than general consumer advertising. Convention booth design and environmental branding require large-format signage production through vendors such as Creative Juices Signage, translating mdg's campaign creative into physical exhibit assets. The agency's attendee acquisition methodology combines variable-data direct-mail printing, programmatic digital retargeting, and email automation sequences calibrated to 90-day pre-event registration conversion funnels.
