About Us

For more than three decades, Project Ninety, Inc. has served individuals, families and the Bay Area community through its residential alcohol and substance abuse treatment services. What began in 1972 as a humble idea has grown into a premier human services organization with over 200 treatment beds. We are a California Alcohol and Drug Programs (ADP) licensed, nonprofit residential substance abuse treatment program with facilities in two Northern California counties (Santa Clara and San Mateo). We provide services to adult men and women whose circumstances are varied. They might be homeless, highly educated/skilled, and straight from prison or jail, unemployable or have limited language skills. All these people have an addiction to substances in common, regardless of their socioeconomic standing, race, cultural background, education, age, or their life experience.
