OPA is celebrating its 75th anniversary in 2021.  We are excited about the momentum and status OPA is gaining among elected leaders.  It is through our members that our advocacy efforts are paying off with great changes to YOU, a psychologist, and to the practice you represent.  

In 2015, The OPA Board of Directors approved the development of a 75th anniversary history of the association.   

Dr. Charles, Whipple, has served as the OPA historian from 1972 - 2018 and has written and updated the "Psychology in Oklahoma" 75th anniversary document through 2018.
