About Us




Susan-BerlinMy mission is to help you discover more of who you are and, through counseling and therapy, help you to work toward personal goals to make your life more fulfilling. My focus will always be on helping you to have a fuller, more authentic, creative, productive and spirited life in and out of your relationships.

Psychotherapy is an art to be practiced and refined, as is life. I am an artist both in my own journey and in my work as a psychotherapist. Let’s open the door to possibilities together and see what we can find inside of you that needs healing and that will bring you to a happier and more fulfilling life.

In 1989, I started working at Caron Treatment Centers in Pennsylvania (then called The Caron Foundation and Chit Chat Farms.) It was there that I discovered my passion and joy in helping people find more of themselves and witnessing the magical results of that journey. At Caron, I worked in the five-day Group Experiential Program that specialized in working with Codependency, ACOA (Adult Children of Alcoholics), Addictions, Childhood Trauma, and issues of feeling stuck in your life.

In 1992, I moved back to New York City (where I was born and raised) to begin my Private Psychotherapy Practice. While establishing my practice, I also designed and implemented an Intensive Outpatient Treatment Program (IOP) for Drugs, Alcohol and Mental Health issues, for Mediplex-United Hospital in New Rochelle, NY.

In 1999, now a decade out of Graduate School, I made a difficult but important decision to relocate to Washington, DC and begin a Private Practice here. It was a big leap to leave my family and all that was familiar to start over, but I was following my heart and listening to my soul which told me it was time to make this change, this leap, and I did it with excitement and wonder.

My work now entails Individual counseling and therapy, couples and marriage and relationship counseling, group therapy, drug and alcohol treatment, psychodynamic clinical supervision for social workers in DC and drug and alcohol counselors specialized work with impaired professionals, athletes and military personnel, both active and retired.
