The P.E.O. Sisterhood was founded by seven young women in 1869 on the campus of Iowa Wesleyan College in Mt. Pleasant, Iowa. P.E.O. has expanded from a small college society to over 250,000 members in chapters throughout the United States and Canada. From its inception, the P.E.O. Sisterhood has taken an active role in the promotion of educational opportunities for women. Education continues to be the only philanthropy of P.E.O., as evidenced by the promotion of five international projects and countless state and local ones designed to assist women as they pursue a college education.

The purpose of this website is to serve Oklahoma P.E.O.'s by sharing information about P.E.O. history, projects, programs, events, and activities relevant to all state members. We also want to introduce you to your state officers who are ready, willing, and able to assist you at any time. Remember, this is a work in progress. Please come back often as new items will continually be added. If you have suggestions for other things you would like on this site, please let us know via the Feedback page.
