Economic Club of Oklahoma

For more than sixty years, The Economic Club of Oklahoma (ECoO) has been a cornerstone for meaningful dialogue and thought leadership within the business community. The ECoO is an assembly of Oklahoma’s top influencers meeting to discuss important economic and social issues. Members not only benefit from access to local experts, but national speakers purposefully selected for their industry knowledge, relevancy and timeliness.

Club objective: To aid in the creation and expression of an enlightened public opinion of the important economic and social questions of the day.

In the winter of 1955, at the suggestion of Hardin W. Masters, a group of businessmen met to discuss forming a club. The principle purpose was a forum for public discussion of current economic and social subjects.

Twelve notable businessmen were selected to form the organization modeled after the well-respected Chicago and New York clubs, and tentatively adopted a constitution and by-laws. Each member suggested five distinguished persons for the original charter membership and began building the organization now known as the Economic Club of Oklahoma.

The ECoO exceeded expectations in its first full year and grew in membership, stature and importance, just as its founders had anticipated.
