Unitas is a voluntary, not-for-profit, behavioral health and primary care clinic licensed by the NYS Office of OMH, the office of OASAS, and via the DSRIP Project 3.a.i, can provide primary care services. It was first organized by Dr. Roman Pabis in 1983 as an Outpatient Mental Health Clinic, specifically for Polish and other East European Slavic population. A few years later, to meet the demand, a chemical dependency program was added that is certified by the New York State Office of Alcoholism and Substance Abuse Services (OASAS). Most recently Unitas added physical health to the services it can provide to the communities of New York City. Unitas also is a strong member of a larger network of outpatient treatment facilities which Unitas works closely with to provide the best care for patients with different levels of treatment needs.
