Personal Statement

I chose primary care because I enjoy the continuity and collaboration that comes from building relationships with patients and their families. In both my primary care practice and my specialty in diabetes care, I am committed to partnering with patients to promote healthy lifestyles, preventative health, and effective self-care.  I feel strongly that this patient-provider partnership is crucial to improving health outcomes and quality of life.
