Expert's Profile

I am a 1975 graduate of the University of California, Berkeley where I obtained my doctorate in psychology. I previously had graduated Phi Beta Kappa and Summa Cum Laude from UCLA, with Highest Honors in Psychology, in 1968. I have been a licensed psychologist in California since 1976 and have never been subject to any disciplinary proceeding. I practiced as a clinical psychologist and manager at The Kaiser Permanente Medical Center in Santa Clara, California for 27 years, beginning in 1980. At Kaiser, I treated a wide range of individuals, including those with “dual diagnoses”—individuals who suffered from a substance abuse diagnosis in addition to a primary psychiatric diagnosis. I was chair of the Psychiatry Department Peer Review Committee at that medical center for 11 years. For the final three years of my time at Kaiser, I managed the Intensive Outpatient Treatment Program (IOP), a day-treatment program for individuals with severe mental illness, including those with co-occurring substance abuse problems.

Since 1993, I have maintained an independent practice in forensic psychology, carrying out evaluations of emotional damages and malingering in civil suits and providing standard-of-care testimony in psychology malpractice matters. I have also carried out numerous evaluations of fitness for duty for license holders practicing under a variety of professional boards in California, as well as for employees of a variety of companies that have retained me for that purpose. I currently evaluate individuals who hold top-secret clearances under the auspices of the CIA, NSA and Department of Defense for fitness for duty. I have served as a Billing Monitor for the Board of Psychology and have offered expert testimony in matters before the Board of Registered Nursing, Board of Pharmacy and Medical Board of California.

I am currently a member of the Panel of Evaluators for the Superior Court of California, carrying out evaluations of competency to stand trial and insanity defense in criminal defendants and am frequently retained as a testifying expert in criminal matters before Santa Clara and San Francisco County Superior Courts. I was formerly a member of the Forensic Assessment Division, Board of Parole Hearings, California Department of Corrections and Rehabilitation, where my duties included the psychological evaluation of life-term inmates regarding suitability for parole in terms of violence risk, including risk of sexual re-offense. I am an evaluator for the Ohio Industrial Commission, Workers Compensation and Disability claims. I have testified as an expert witness in Federal Court on behalf of the Indiana State Board of Law Examiners.

I am a published expert in the field of psychotherapy ethics, having published numerous articles in peer reviewed, professional journals. By virtue of my professional contributions to the field of psychology, I was elected a Fellow of the American Psychological Association, an honor that is according only about three percent of members of the APA.

In 2011, I became an Approved Psychological Competency Evaluator, United States Immigration and Customs Enforcement, Enforcement and Removal Operations, San Francisco Region. I have evaluated numerous United States citizens with regard to sexual deviancy as applicable to the Adam Walsh Act, as well as evaluations for those seeking I-601 Waivers, those seeking waivers under the Violence Against Women Act, and those seeking "U" visas as victims of crime.

I am currently the psychological consultant to the Campbell Police Department Crisis/Hostage Negotiation Team and serve on the State Bar of California Lawyer Assistance Program.
