The Massachusetts Department of Public Health currently operates a Joint Commission accredited, 350-bed facility at Tewksbury Hospital, providing both medical and psychiatric services to challenging adult patients with chronic conditions. The Public Health Museum in Massachusetts now occupies the Richard Morris Building. In addition to the hospital and museum, the Tewksbury Hospital campus also hosts eight residential substance abuse programs, serving up to 275 patients. Five Massachusetts state agencies also have regional offices at Tewksbury, including the Massachusetts Department of Mental Health and the Massachusetts Department of Public Safety. The campus also hosts several non-profit and for-profit private entities, including the Lahey Health Behavioral Services' Tewksbury Treatment Center, Casa Esperanza's Conexiones Clinical Stabilization Services (CSS), the Lowell House's Sheehan Women's Program, the Lowell House Recovery Home, the Middlesex Human Service Agency, and the Strongwater Farm Therapeutic Equestrian Center.
