Yakima, Washington is a city of 80,000 in central Washington, with a regional population of 229,000.  The economy is based on agriculture, including apples, wine grapes, hops and craft beer production, and row crops.

I am a board-certified psychiatrist, a board-eligible child psychiatrist, and a certified group psychotherapist.   Psychiatrists have medical training and prescribe medications when appropriate. I provide individual psychotherapy, group psychotherapy, psychiatric treatment evaluations, complex independent medical evaluations, and do regular writing and research. I have a 20 year involvement with occupational psychiatry, and provide organizational consultation and executive coaching.

A Psychiatric Evaluation requires 90 minutes face to face. As an additional part of the evaluation the MMPI-2 or MMPI-2-RF is administered by computer which requires an additional 60-90 minutes. The findings are explained to the patient in the evaluation encounter. I have formal training in the administration and interpretation of the MMPI-2 and MMPI-2-RF and have published peer reviewed papers and chapters that discuss its use in this context.

Psychotherapy is usually undertaken on a one time per week basis at the beginning of treatment. All treatment plans are discussed with the patient. My theoretical orientation is psychodynamic and analytically oriented with an emphasis understanding and changing "here and now" feelings and behavior. Treatment may be brief, intermediate duration or long term, depending on the problems being addressed and patient preference.

Occupational Psychiatry, including the evaluation and treatment of patients with workplace injuries is a major interest of mine, and I have authored peer reviewed invited papers and chapters in the field from 2000 through the present.

Independent psychiatric evaluations (IME's) conducted both for plaintiff and defense attorneys, particularly within the Worker's Compensation arena, and also including personal injury evaluations. I perform Psychiatric treatment consultations at the request of physicians, both privately and at the request of the Department of Labor and Industries.I am trained in the administration and interpretation of the MMPI-2 and MMPI-2-RF and they are administered to all evaluees routinely. Consult my 2010 Harvard Review of Psychiatriy article and the soon to be published chapter in the 3rd Edition of Medical Care of the Psychiatric Patient, Fogel and Greenberg Editors, New York, Oxford Univeristy Press for more technical information regarding psychiatric assessment.

Insurance --  I am in the Premera Blue Cross (most plans) and Regence (most plans) preferred provider networks. I am a psychiatric provider for the Washington State Department of Labor and Industries and a consultative examiner for Disability Determination Services of Washington State.

Research: I initiated a multi-year research project assessing the relationship of various scales of the MMPI-2 and MMPI-2-RF to subject characteristics in a population sample of >500 which will attempt to determine if any scales are predictive of a positive or negative response to psychiatric treatment. I also hope to use serial data collected on persons over the course of treatment (anonymously) to measure the efficacy of different forms of psychiatric treatment for specific diagnoses with and without co-morbidity (more than one diagnosed psychiatric condition). I have received in-kind support from the University of Minnesota Press for this project.

"Tips for Conducting Disability Evaluations" in May 2014 Psychiatric Times by C. Donald Williams MD CGP and Greg Couser MD.

Group psychotherapy, including cognitively and analytically oriented individual psychotherapy groups for adults. 

I offer Organizational Consultation,  assisting public or private sector companies with up to 500 employees that are experiencing a business threatening crisis--either with a key employee or with the organization as a whole.

Executive coaching designed to maximize leader effectiveness.  Executive coaching focuses on improving leadership skills, drawing upon the existing strengths and talents of the individual, and developing strategies for improving leadership effectiveness.

Disability information


Preventing Needless Work Disability by Helping People Stay Employed--this document (in .PDF format) addresses how Worker's Compensation programs could be improved to promote injured worker health and functioning and also provide more effective medical care and improved claims management. This document was subsequently modified by the ACOEM board, and their version can be viewed on their website.  I contributed to this report from the Stay at Work/Return to Work Committee. It is the product of more than two years of effort, and was spearheaded by Chairperson Jennifer Christian M.D., CEO of Webility Inc.
