Choosing a therapist and getting started itself can be overwhelming. I believe that treatment must be specific to the person and the problem and be based on a broad array of available clinical modalities and interventions. These interventions are always provided with safe, supportive and professional care. I have over twenty years experience as a psychologist and as a supervisor and trainer of therapists from all of the mental health fields. I head a group private practice with many available resources for adults and children. I am a leader in the field of abuse and trauma as well as sexuality and relationships.
Some of my credentials include: Diplomate and Clinical Supervisor of the American Board of Sexology; Diplomate and Certified Sex Therapist of the American Association of Sex Educators, Counselors, and Therapists; and, Master Addiction Counselor by the National Certification Commission for Addiction Professionals.
I am also a Diplomate and Fellow of the American College of Forensic Examiners. Please contact my practice for a full array of specialized services for adults, families, and children.
