"It is my pleasure to introduce the CASASTART^sm Field Guide: A Proven Youth Development Strategy that Prevents Substance Abuse and Builds Communities. The CASASTART^sm Field Guide is the result of nine years of research, experience and evaluation in cities across the United States, where this program has enhanced the capacity of communities to serve high-risk youth through formal partnerships that reduce their use of drugs and alcohol and promote their positive development.." -- Joseph A. Califano, Jr.
