The Leo A. Hoffmann Center began operation in November 1979 as a program for juvenile delinquents in response to a growing need for residential treatment services identified by the Brown and Nicollet County Human Services Board. In 1983, the Center became a private, non-profit corporation specializing in the treatment of adolescent males who engaged in inappropriate or harmful sexual behavior. Organizational downsizing, as well as programmatic and organizational restructuring created opportunities for the formation of improved, comprehensive, strength-based, multi-modal, multi-disciplinary, and individualized, treatment facilities. Program staff from Evergreen and North Cottages continue to focus on creating and maintaining safe environments for clients and staff in order to promote a sense of belonging, pro-social learning, and positive change.

Each building is equipped with thirteen single bedrooms and one triple bedroom. Both buildings have the capacity for 16 clients. Security cameras are located in the triple bedrooms, living unit, commons area, kitchen, and laundry room to enhance security and supervision measures.

Outpatient Services (St. Peter Counseling Center) were added in 1984 and expanded in 2007 to provide sexual behavior assessments, as well as group, client, and family therapy to adolescent males with problematic sexual behavior.
