The original Center for Attitudinal Healing was established in Tiburon, California, located on the dock on San Francisco Bay. From there, the creation of the very first Peer Support Group model emerged, welcoming siblings, parents, adolescents, and adults dealing with illnesses like cancer and later, AIDS, as well as those facing everyday life-changing situations. The nonsectarian philosophy of Attitudinal Healing emphasizes that all are welcome, and the multiple services and programs have remained free of charge to this day.
