Our Doctors

Our approach to chemical dependency is different from any addiction treatment program in New York City. Our doctors provide confidential, comprehensive care in one setting that is tailored to the individual. Our emphasis is on the integration of a psychotherapeutic approach with a limited and careful use of medication.Unlike many psychiatrists that only prescribe medication or programs that can only offer therapy, our practice is based on the research-proven fact that patients who require mental healthcare respond best to a combination of therapy and medication. At Fifth Avenue Psychiatry, you do not have to be referred out to someone else for “medication management.”
