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 Stephen to seek solace of an unusually potent nature. He started to use heroin, and by age 18 was in full addiction.
Around this time, Stephen’s grandmother read an article about Dr. Daniel 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 Yohays 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 Gehrig'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, Stephen 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. Stephen held the NYS Credentialed Alcoholism and Substance Abuse Counselor (CASAC) credential for many years and now after forty-six years working in the field of substance abuse treatment, he holds the prestigious honorary designation of Counselor Emeritus.
