My mother, grandmother and a few other women on my mom's side were all PEO members. They would never tell me what PEO stood for. I know its divided into chapters. I believe my mom was in Chapter F. They met once a month for lunch at a members house. Never thought much of it. I always thought it was just a social club. Their lunches were not secretive or anything. I can press her for some more info. She asks me for Q updates all the time. She is woke.
