Mission Treatment was formed in 2003 by Marc Lewison to provide substance abuse treatment services.
The Company’s initial startup targets were in two high growth areas within San Diego County. The first clinic, located in Escondido, began operation in July 2004 to serve the growing North County region. The second clinic, located in San Diego, began operation in April 2005 to serve the city area, San Diego.
The two new Mission Treatment clinics were the first new clinics in San Diego County in over twenty years.
In March 2007, Mission Treatment acquired a system of 5 programs owned and operated by New Life Medical Center and Life Improvement Center. The programs are established in operating clinics located in Arizona, Nevada, and Oklahoma.
The acquisition combined with the 2 existing California clinics expanded Mission Treatment’s operations to 7 clinics in a 4 state area. In September 2014, Mission Treatment opened it’s the third clinic in California in the north San Diego County city of Oceanside, for a total of 8 clinics in the Southern and Western United States.
