About ACI

For more than 40 years, Addiction Care Interventions (ACI) has been the leading provider of chemical dependency treatment.  ACI prides itself in its holistic approach to treating individuals suffering from addiction and their families who are impacted by addiction. As the nation’s oldest private substance abuse treatment facility, ACI continues to provide cutting-edge medical, psychological, and spiritual services under the same mission; our unwavering commitment to treating patients who are chemically addicted, while providing their families with care, hope, and guidance.

The overarching goal of treatment at ACI is to improve our patients lives in all areas of life: physical, emotional, familial, occupational, and social. This is accomplished in a patient-centered, trauma-informed therapeutic environment. Our comprehensive, individualized, and integrated services are provided by an interdisciplinary team comprised of board certified Addiction Psychiatrists, Addiction Medicine Specialists, Internal Medicine and Family Medicine Physicians, as well as Nurse Practitioners (NP), Physician Assistants (PA), Psychologists, Social Workers, CASAC, RN’s and LPN’s.

At ACI, our team is qualified to treat adolescents, adults, and seniors in both inpatient and outpatient programs. Individual, group, family, and couples counseling are offered to both our patients and their families during the course of treatment and beyond. Cognitive Behavioral Therapy (CBT), Rational Emotive Behavioral Therapy (REBT), Dialectal Behavioral Therapy (DBT) and Scheme Therapy are just some of the counseling modalities used to meet the individual needs of our patients. Medical, psychiatric and detox services are also provided to ensure that the care we provide is comprehensive and complete.

Our employees are required to remain current in their respective fields and pride themselves in the evidence-based programming they provide.

ACI is accredited by the Joint Commission on Accreditation of Healthcare Organizations (JCAHO), and the NYS Office of Alcoholism and Substance Abuse Services (OASAS).

For every patient, our team creates an individualized treatment plan to ensure the highest rate of success. It is this collaborative approach to care that we believe is the secret to ACI's continued reputation as New York’s premier center for chemical dependency treatment services.  

ACI’s chemical dependency program was originally designed by the world-renowned Psychiatrist Daniel Casriel MD (1924-1983). After his passing, Dr. Casriel’s protégé and former patient, Stephen J. Yohay, assumed leadership of the company and significantly expanded programming and ACI's reputation. Mr. Yohay currently serves as ACI’s President and Chairman of the Board of Directors.  

Our Chief Executive Officer, Warren D. Zysman LCSW-R, CASAC, graduated from Fordham University School of Social Work where he specialized in Substance Abuse. He received advanced training from Aaron Beck, MD, at the Beck Institute of Cognitive Behavioral Therapy and Research in Pennsylvania and Albert Ellis, PhD, at the Albert Ellis Institute for Rational Emotive Behavioral Therapy in New York City. Mr. Zysman has used his training in conjunction with over 17 years of experience to help make ACI the most comprehensive, evidence-based practice treatment service available in New York.

Types of Therapy

"I used to be a successful teacher. I was proud of myself and my achievements. I started using drugs and hit rock bottom. Then a friend took me to ACI. I went to detox and rehab. I am currently enrolled in the outpatient program and am doing great. I love where I am living and I love the staff at ACI. I am so grateful for the fellowship I have with my peers. I look forward to going to groups, seeing my counselors and the friends that I made. My favorite thing is “Jump Start Café” on Friday morning. I am learning how to have fun without using. I finally feel lucky to be alive.”
