Carnegie Hill Institute (CHI), established by Dr. Harvey D. Karkus in the 1970s, provides comprehensive addiction treatment services in New York. Their specialized opioid treatment center operates weekday mornings and Saturday, offering medication-assisted treatment with methadone, Vivitrol, Suboxone, and buprenorphine to help manage withdrawal symptoms. This program integrates regular counseling services—individual, group, and family sessions—alongside telehealth options and dedicated aftercare support to address the underlying causes of opioid dependence. The institute also maintains a separate chemical dependency outpatient program, available weekdays from 9AM to 6PM. This program serves individuals struggling with alcohol and other substances through multiple treatment approaches including anger management, an impaired drivers program, and intensive outpatient services. Both individual and group therapeutic modalities are available, with select services accessible via telehealth. New clients begin their treatment journey with an admission screening conducted by phone or online, followed by scheduling an in-person intake assessment to determine the most appropriate care plan.
