Co-Dependents Anonymous (CoDA) is a twelve-step program for people who share a common desire to develop functional and healthy relationships. Co-Dependents Anonymous was founded by Ken and Mary Richardson and the first CoDA meeting attended by 30 people was held October 22, 1986 in Phoenix, Arizona. Within four weeks there were 100 people and before the year was up there were 120 groups. CoDA held its first National Service Conference the next year with 29 representatives from seven states. CoDA has stabilized at about a thousand meetings in the US, and with meetings active in 60 other countries and several online that can be reached at www.coda.org.
