A.R.E.B.A. Casriel, Inc. [ACI] was incorporated 1981 and has been treating the illness of substance abuse and addiction for over thirty years.

Early History

In the 1960's, New York City psychiatrist Daniel Casriel was cofounder and psychiatric architect of Daytop Village, a private drug rehabilitation center. With a grant from the National Institute of Health to study such centers across America, Casriel paid special attention to California-based Synanon and opened his own treatment facility, ACI.

Steven J. Yohay entered treatment with Dr. Casriel in 1971 for heroin addiction. He was sufficiently successful in recovery and showed sufficient promise in his grasp of treatment principles that he quickly began training as a counselor. Within four years, he had become Director and now serves as President and CEO. Under his direction, ACI has grown to over twelve times its original size. (Steven J. Yohay Wiki Link)
