Stephen J. Yohay

President/Chairman of the Board

Born and raised in the Bronx, Stephen graduated valedictorian from DeWitt Clinton High School at age 16. At seventeen, a fateful automobile accident changed the course of his life; losing his wife-to-be and witnessing her decapitated form led the young Yohay to seek solace of an unusually potent nature. He started to use heroin, and by age 18 was in full on addiction.
Around this time, Yohay's grandmother read an article by Dr. Casriel, a New York Psychiatrist who had extended his private practice to include a dozen beds for the private non-state funded treatment of young addicts whose families were in a position to afford such care. Through special arrangement with Dr. Casriel, who was moved by Stephen's mother's plea, "am I not as entitled as a rich person to see my son live?,” the Yohay’s got their son admitted, though the treatment still ate up the family's life savings.

His resolve to find a cure for his condition manifested early and was rewarded with successful completion of his treatment. Stephen had so impressed the staff with his precocious grasp of substance abuse theory as well as an infectiously personable nature that he became Dr. Casriel's personal protégé as a counselor trainee. Through hard work and devoted attention to the clients, Stephen rose to become clinical director by 1975.

Dr. Casriel was tragically struck down by Lou Gherig's disease (ALS) in 1983. Stephen, by this time a principal of the company, envisioned a significant expansion of the treatment center, and moved it to a larger building at its current home on 57th Street.

Having assembled a cast of talented managers, Yohay built ACI into the premier facility for substance abuse treatment in the New York area, currently standing as the oldest private facility for such treatment in the country. As president and principal shareholder of ACI, Stephen now oversees treatment of 6,000 patients per year. He expresses gratitude at his fortune in having been able to transform such adverse youthful circumstances into a thriving healthcare facility giving a second chance to so many individuals who suffer from the disease of alcoholism or substance abuse.

“I firmly believe that ACI is why my son is still alive, back with our family, and back to school. As a mother my primary concern was that my son would receive compassionate care and the attention he needed to focus on his recovery. We have been through this before and I was losing hope, so was my son. It is a very lonely and dark place to be. All ACI staff, doctors, nurses, and counselors were always available when I had questions. We were able to visit and we had a family therapy session where I learned that I had to take care of myself too, without feelings of guilt. We also learned how to set limits and boundaries. At last, freedom, from the emotional pain of being part of an addicted family. My son learned the skills he needs to sustain his sobriety. He learned about the importance of maintaining sober friends and activities. He learned how to say no and change the things in his life that kept holding him back from happiness, health, and success. Thank you ACI I have my son back!”
