I am not accepting new patients at this time. You are welcome to check back here later to see if my schedule has opened up.
My practice is limited to individual adults age 21+. My areas of practice are clinical and rehabilitation psychology. I do not see couples or children. I have extensive experience treating adult survivors of abuse, and in 2024 I published a book on this subject: Infectious Misbehavior, available from Amazon.
I am a clinical psychologist with a doctorate (Psy.D.) in clinical psychology and two master's degrees (M.A. and MSW). I have practiced psychotherapy since 1982. My principal mode of treatment is cognitive-behavioral therapy. I do not accept clients for services who are engaged in legal disputes regarding injury or disability compensation.
