Wyoming P.E.O. is a group of almost 3,000 women in 65 chapters. These women dedicate their time, talents and resources to build stronger communities and improve the lives of those around them. These resources are intended to make that work easier and more productive. If you are serving as a local chapter officer, most of the information you need is located in the Instructions to Officers of Local Chapters (IOLC) and in the P.E.O. Constitution.
