Our Story

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.

About Our Office

The World
Class Hospitality


"Our Mission is to provide the best total health care to all individuals in the communities of New York City suffering from mental health, addiction, or physical health problems. Unitas works to aide every patient in reaching their individual goals, dreams, and helping all patients have the best quality of life possible and aim to do this in a very open, accepting non-judgmental, and friendly environment. What sets St. Mark’s Place Institute for Mental Health, Inc.(also known as Unitas) apart from other clinics is Unitas has a unique integrated approach to health problems. Patients’ mental health and physical health are evaluated separately and a combined total treatment plan is developed. Providers work closely together, discussing new findings, how one aspect of a patient’s health will affect another, and how to best take care of the patient. Unlike other clinics, Unitas prides itself on providers working face to face in the same building to develop a plan and often even sitting in on each other’s appointments to help coordinate care."
