The Hermosa Five-O Senior Activity Center opened in May of 2010 and is open to all South Bay Residents who are over the age of 50. Hermosa Five-O members are a group of fun, active and motivated people, who continually strive to improve their lives and their community. We believe it is important to stay healthy, continue to learn, and have fun each day so we do our best to program a variety of activities to help us to live a balanced life: physically, emotionally and mentally.
