About us

Dr. Fader and Dr. Dulchin have been friends and collaborators since 2001, and have used their own collaborative relationship to model how psychotherapy and psychopharmacology can and should work together.

We both emphasize a practical and respectful approach to patient care, and know from our combined 32 years of practice, and from our past clinical collaborations, that communication, flexibility, practicality, openness and a sense of humor underlie almost all successful treatments.

Our staff comes from a wide variety of training backgrounds, but all of us aim to work with you to build on your existing strengths while helping you develop new strategies and behaviors for overcoming adversity and living the most satisfying life possible.
