Project Transition provides specialized care for adults aged 18-65 struggling with mental health conditions, including those with co-occurring disorders such as substance use, intellectual developmental disorders, or physical health conditions. Their Nashville location, operating at Haven Apartments (formerly Woodbridge Apartments), offers both residential and day treatment options in an apartment setting. What distinguishes Project Transition is their therapeutic community approach to mental health treatment. They intentionally refer to participants as "members" rather than clients or patients, fostering a sense of belonging and community integration. This model aims to reduce stigma while promoting normalized social expectations within the apartment complex community. The program utilizes dialectical behavior therapy (DBT) with an individualized, strength-based focus. A dedicated team of approximately 30 professionals, including certified peer and recovery specialists, provides daily support from 7 a.m. to 9 p.m., with emergency assistance available after hours. The treatment approach incorporates evidence-based interventions tailored to each member's specific goals. Daily programming includes skills workshops, medication management, individual therapy sessions, group therapy twice weekly, community meetings, goal planning, and access to Alcoholics Anonymous and Narcotics Anonymous meetings. An onsite driver helps transport members to off-site recovery meetings and medical appointments. Project Transition also offers Systems of Support (SOS) for children and adults whose behavioral health concerns impact their community functioning. This service works alongside crisis teams and family support systems to reduce hospitalizations and prevent crises. The partially furnished apartments allow members to bring personal belongings, creating a more homelike environment. While family and friends are welcome to visit during daytime hours with housemate approval, overnight stays are not permitted. Through this structured yet supportive approach, Project Transition measures success across 13 specific criteria designed to track members' progress toward meaningful community integration and recovery.
