The Rotary Club has 752,000 members in 150 countries. It was started in 1905 by a group of businessmen for their mutual benefit. The name derives from the original plan to "rotate" the location of each meeting. Today Rotary is a club devoted to four types of service: Club, Community, Vocational and International. We are still growing and add at least one new club to our worldwide membership every day. Tri-Valley Area, Northern California
