Philosophy of Care

I am strongly committed to improving the health and well being of children and adolescents with a wide variety of endocrine conditions.  It is important to provide patients and their families with a comfortable environment to discuss medical diagnoses, management and treatment options, and allow for informed healthcare decisions.  I enjoy building lasting relationships with patients and their families and I work hard to provide the highest quality of care for my patients.

Clinical Interests

I value medical education and public service, and strive for excellence in theses areas.  My involvement in the Pediatric Endocrinology Telemedicine clinic provides services to patients living in rural areas of Northern California as well as Oregon.

Research/Academic Interests

My subspecialty training included stem cell research and treatment for diabetes mellitus.
