I’m a clinical psychologist specializing in understanding relationships, both with yourself and with others. I graduated from a psychology doctoral program in 2004 and have worked at psychiatric and health rehabilitation hospitals, community mental health center, and long term care facilities, treating adolescents, adults and seniors. I have had a full- time private practice for over 13 years.
My training and practice is psychodynamic, which focuses on understanding how you are feeling in the moment, and making connections between your past and present. The people I work are feeling emotional pain and tend to struggle with mood disorders, relationship issues, loneliness, low self-esteem, and difficulty managing strong feelings.
We will start with an initial appointment so I can hear more about what brings you to therapy and you can understand what I offer. Then I can make recommendations for your treatment. If you agree to a course of therapy, we can develop treatment goals together.
