We turn intent into execution.
about Group Theory Co.
Founded by Annie Freedman and Evie Callaway Rino, Group Theory Co. brings more than two decades of combined experience across private clubs, hospitality, entertainment venues, and large-scale member environments — spaces where community either works, or falls apart, in real time.
We’ve worked inside country clubs, city clubs, social clubs, stadium clubs, hospitality brands, and high-growth organizations. We understand how membership, programming, operations, and revenue must work together because we’ve led them from the inside.
