Our values


our history

Leading the way in community mental health treatment, Dr. Richard Brotman founded the Center for Comprehensive Health Practice (CCHP) in 1960. Following the passage of the Community Mental Health Centers Act of 1963, CCHP staff established the Division of Community Mental Health at New York Medical College, and played a crucial role in the development of the nation’s first federally funded community mental health center at Metropolitan Hospital Center.

From its very beginning, CCHP carried out cutting-edge research in substance use treatment, primary care and supportive services. Beginning in the 1970’s, CCHP incorporated interdisciplinary primary care into its model, with physicians and clinicians from multiple disciplines working side-by-side to address both the medical and psychosocial issues affecting each person. Through this model, our providers and counselors recognized the importance of case management needs, such as vocational services to enhance successful substance use treatment and integrated these services into our treatment model.

In 1990, CCHP was incorporated as a separate not-for-profit community health center currently located within Metropolitan Hospital Center.


Our Approach to Care

To best serve our patients, we use a community health, team-based approach to provide individuals and families with an array of specialty services. Our extensive team of social workers, pediatricians, nurses, internists, family practitioners, psychiatrists, playroom teachers and vocational counselor all work together to address the physical, emotional and social needs of our patients and their families.



Our services are available to anyone regardless of one’s race, ethnicity, gender, sexual orientation, religion, age or ability to pay. We gladly accept Medicaid, Medicare and most private insurances. We also offer an income-based sliding scale.

From its very beginning, CCHP carried out cutting-edge research in substance use treatment, primary care and supportive services.
