At Three Rivers Midlands, we never forget that patients are people. People with potential. People who can have better relationships and live more productive lives. People who need differing levels of care at various stages of life. Three Rivers Midlands is a 64-bed comprehensive mental health facility specializing in residential treatment and partial-hospitalization services. We treat male and female children and adolescents ages 6- 21 and provide treatment for psychiatric, addictive and substance abuse related illnesses.
