Day Treatment

The Day Treatment Center is a structured setting that provides individuals with a daily program of therapeutic and social activities. Participants are offered a variety of activities with their group, in the community, and in daily psycho-educational sessions. Activities are structured according to an individual's treatment needs and choices.


Group therapy topics and activities include: interpersonal relationships, self-esteem, anger management, the place of humor in mental health, men's and women's issues, horticultural therapy, nutrition, exercise, and more. The center uses evidence-based practices to create a friendly, non-threatening atmosphere for these activities, which can promote better learning and personal growth.
