“Today is only one day in all the days that will ever be. But what will happen in all the other days that ever come can depend on what you do today.” ~Ernest Hemingway, For Whom the Bell Tolls

Welcome. I am pleased to provide individualized, outpatient psychiatric services to adults, specializing in the treatment of mood disorders (depression, bipolar disorder, mood fluctuations, irritability), anxiety disorders (generalized anxiety, panic, phobias, obsessive-compulsive disorder, social anxiety), psychotic illness (schizophrenia), substance abuse, relationship difficulties, and other emotional or cognitive struggles. Because of the small size of my private practice, I am able to provide a very high level of care and attention that helps to foster your recovery. Life can be difficult, but you don’t have to suffer when there is help available. Please take a look through my website and call me today for a complimentary phone consultation to see if I might be of service to you.

I am a proud member of the following professional organizations:

  • American Psychiatric Association
  • Association of Gay and Lesbian Psychiatrists
  • Doctors without Borders
  • Orange County Psychiatric Society
  • Physicians for Social Responsibility
