ABOUT YOUR PHYSICIAN                             

Think clearer.  Feel more.  Fear Less.  TM

As a Special Forces flight surgeon turned psychiatrist I discovered early in my medical career that there truly is no health without mental health.  With the constant deployments in my military unit on clandestine missions, I observed how stress in a family member can jump from person to person and lead to physical illness as well.  After 5 years of active duty and 9 of total service, I left the military to get the training to become a board certified psychiatrist.

I provide  a complete gamut of services for full recovery from stress, depression, and problems with relationships, as well as recovery from the more serious conditions such as bipolar disorder, substance abuse, and schizophrenia.  I combine my 24 years experience and extensive knowledge of advanced therapy techniques, medications, exercise, and life coaching, with your unique experience and goals, to get the recovery you want in the least amount of time. You won’t have to be bounced between different offices here.

I believe the quicker you get effective treatment the faster and easier your recovery will be.  I have tremendous experience across the age spectrum too, and treat patients from 13 to end of life.  I work with individuals, families, and couples in therapy.  Procrastination with stress and thinking and feeling problems, just like other medical conditions, only leads to unnecessary suffering and lost time. I want to help you be your best.

I serve in a number of leadership positions.  I earned the honor of Distinguished Fellowship with the American Psychiatric Association in 2003, awarded for both excellence in psychiatry, community service and leadership which only 19% of members achieve in their lifetimes. I am the vice chairman of the APA’s Council on Communications, and take very seriously my role in public education.  I am a regular contributor to Health This Week (healthtelevision.com) and have appeared on CNN, Today Show, and many cable TV outlets.  I am a past president of the Orange County Psychiatric Society, and continue to serve on both the Board of OCPS and of the Orange County Medical Association.  I have provided a two hour a week, free, open-to-the-public group for families dealing with a mental illness called Interactive Solutions for the past 15 years.

My service in the military included a general surgery internship at David Grant Medical Center at Travis AFB, CA followed by assignment to the 8th Special Operations Squadron as a flight surgeon, at Hurlburt Field, FL.  I served in both the First Gulf War and Panama Wars, among other operations, and received two Meritorious Service Medals and was the 1988 Flight Surgeon of the Year within the First Special Operations Wing.

I am a graduate of Deerfield Academy (1978), Tufts University (1982), Tufts Medical School (1986), General Surgery Internship at Travis AFB, CA (1987), and Residency in Psychiatry at UC Irvine (1994).
