I have been working with clients as a psychologist since 1985. I began my work in public mental health clinics as a child and adolesccent therapist. In 1988 I opened a private practice in Conyers, Georgia and continued working with children, adolescents and families. I am very excited to have begun working with the Pine River Psychotherapy Associates in April 2006. I share my colleagues' committment to experiential, here and now therapy in helping people find solutions to the problems they face. I enjoy working with individuals, couples and families.

I am a native of Atlanta and have been married to my wife Deborah for thirty years and have a daughter Kate. I enjoy architectural design, woodworking and fly-fishing.


General private practice of clinical psychology with preadolescents, adolescents, and adults in individual, family, couples and group therapies.

Supervision and other consultations available.

My colleague, Dr. Marlyne Israelian, and I are offering group psychotherapy sessions for young adults struggling with a variety of problems that are unique to this phase in life. Group meets every Thursday at 6:15. Please contact us for more information.
