#3 in PR Agencies
of 16 ranked entries
Global network (Omnicom) · Founded 1946
FleishmanHillard built its reputation from a St. Louis base into a genuinely global network under Omnicom, with a particularly deep public-affairs and government-relations practice that many peer firms treat as a smaller sideline. Recorded specifics: founded 1946, headquarters St. Louis, USA, structure Global network. Panel highlighted particularly deep public-affairs and government-relations practice, long, stable operating history spanning nearly eight decades and strong global network reach through Omnicom’s broader infrastructure. The reservation on record is omnicom ownership limits full independence relative to boutique specialist firms.
