Douglas Zimmerman
Psychotherapist in NYC
I’m a licensed psychotherapist with over 25 years of experience in mental health, including 20 years in private practice here in Manhattan.
My work focuses on helping adults manage OCD, ADHD, ASD, and the related mood disorders — often when other treatments have fallen short.
I combine traditional talk therapy with innovative approaches, including Ketamine-Assisted Psychotherapy, to provide care that’s grounded, flexible, and built around each client.
