I am committed to delivering compassionate, evidence-based care to my patients. My focus is on patient education and individualized treatment. Each patient has unique health needs. I work with them to develop care plans that meet those needs and support their overall well-being. In my research, I’m interested in understanding how to prevent disease and improve patient outcomes.

My goal is to bring my knowledge of medicine and experience as a health care professional to every encounter in order to work with my patient's unique understanding of her body and life experience. Together, we can address her concerns and improve health. It is an incredible privilege to help in a time of need, to celebrate a birth, to support well-being. I enjoy learning about people and their health goals and then working with them to reach those goals. I learn from my patients all the time and hope they can learn from me. Helping medical students, residents, and others develop their professional skills is also an important and rewarding part of my work. Working as part of a team allows all of us to do our best.
