The idea of OA came to founder Rozanne S. at a Gamblers Anonymous (GA) meeting she attended with a compulsive gambling friend in 1958. As GA members shared their stories, she heard her story—not of gambling, but of compulsive overeating. She knew then that the Twelve Step and Twelve Tradition program founded by Alcoholics Anonymous (AA) and modeled by GA offered her a chance to change her life and reduce her 152-pound (69-kg) body to a size that would fit her 5-foot, 2-inch (157-cm) frame. Not until 1960, when her weight had increased to 161 pounds (73 kg), could she find other people who shared her convictions. Her chance meeting with a new neighbor, Jo S., gave Rozanne strength in numbers, even if it was only one person. Together they found another compulsive overeater, Bernice S., and convened the first OA meeting in Los Angeles, California, on January 19, 1960.

Today, about 6,500 OA groups meet each week in over 75 countries. With 60,000 members worldwide divided into ten geographic regions and a virtual region, OA helps thousands of compulsive eaters find new life in recovery. For more on OA’s history, read Beyond Our Wildest Dreams.
