This 18-week program is designed to meet the needs of those with a more serious substance abuse problem but who do not require 24-hour care. Clients participate in daytime or evening groups that meet 3 hours a day, three times a week. The program consists of two phases. In the first phase, the client participates in three, 3-hour groups per week for approximately 10 weeks and most often also sees their primary counselor for a weekly individual session. In phase two, the client moves to a weekly 1 1/2 - hour group with individual counseling sessions provided on an as needed basis.
