Personal Message to You:
Thank you for stopping by.  You may be facing some difficult times at the moment.  If so, I would like to invite you to take a step forward in helping yourself to heal.  Please contact me.  I am a cognitive-behavioral therapist who is passionate about helping individuals learn to manage and overcome anxiety, trauma, stress, and depression.

Professional Bio

I received an undergraduate dual degree in Biology and Psychology from the University of Georgia as part of the Honors Program .  I earned my PhD in Clinical Psychology from the San Diego State University/University of California-San Diego Joint Doctoral Program .  I pursued a clinical specialization in the treatment of adult anxiety and traumatic stress disorders through practicum work at the VA San Diego Healthcare System Anxiety Disorders Clinic and PTSD Clinical Team.  I received specialized training in Prolonged Exposure (PE) and Eye Movement Desensitization and Reprocessing (EMDR) , and I am a certified Level 1 EMDR provider.  I completed my clinical internship at the Memphis VA Medical Center and continued to pursue a clinical specialization in the treatment of traumatic stress disorders. There, I completed VA training and certification to deliver Cognitive Processing Therapy (CPT) , an empirically-supported cognitive-behavioral treatment for PTSD.   I returned to California in September 2013 to begin a T32 Biobehavioral Research Fellowship in the Department of Psychiatry and Behavioral Sciences at Stanford University School of Medicine under the mentorship of Dr. Amit Etkin . My postdoctoral research encompasses brain imaging approaches to characterizing heterogeneity in posttraumatic stress disorder, neural mechanisms underlying the therapeutic effects of prolonged exposure therapy , and investigation of novel computerized cognitive and affective training interventions for individuals with PTSD .  As a licensed clinical psychologist, I enjoy working with clients while  delivering evidence-based psychotherapeutic interventions for treatment of anxiety, traumatic stress, and mood disorders.  
Personal Interests
I believe the personal "fit" between a client and therapist is an important aspect of the therapeutic relationship. To that end, I'd like to provide you with a bit of personal information about me.  Outside of clinical psychology and research, I enjoy socializing with friends and family; reading books about spirituality, meditation, Buddhist philosophy, and social dynamics; playing guitar; gardening; regular stress-relieving floats in flotation tanks; trying new restaurants in San Francisco; entertaining my feline companions, Molly and Ranger; camping; hiking; travel; and swimming.
My Philosophy
My philosophy and approach to assessment and treatment is guided by the following principles:
  • Ethics  I aim to provide the highest-quality, ethical treatment possible while empowering the individual to make informed decisions regarding their treatment process and their post-treatment plan for continued improvement and well-being. I adhere to the American Psychological Association's Ethics Code at all times.
  • Rigor  I utilize the most up-to-date clinical research findings to inform my approach to treatment and psychotherapy.  I believe that a successful therapeutic approach begins from scientifically-proven methods and is then tailored to the uniqueness of the individual.
  • Compassion   I believe a beneficial therapeutic relationship between client and therapist is built upon mutual respect, empathy, and compassion.  I am, first and foremost, a human being in interaction with another human being.
  • Integration   I believe the most effective treatment is holisitic, client-centered, and integrates techniques and methods from multiple schools of thought.  There is no "one size fits all" when it comes to the individual's growth or healing process.
