A Warm Welcome

It is truly an honor to work as a psychotherapist and to have the opportunity to witness people as they go through the healing process. I am continually amazed by people’s ability to transform their suffering into joy and to find meaning even in their most painful experiences. By developing compassion and forgiveness for oneself and others, I believe anyone can create a more fulfilling life.

I am a licensed psychologist with good credentials, including a Psy.D. from Stanford and an MA from Columbia, as well as great work experience in community mental health, managed health care, hospital settings, and private practice. More important than my education or resume, however, is the wisdom I have gained from working with people from all walks of life.  What I have learned from the hundreds of stories people have shared with me over the years is that we all struggle, but that we can heal and grow from our experiences.

People truly are resilient.
