Yale Health

Internal Medicine Clinicians

I love getting to know my patients over time and believe strongly in the philosophy of primary care. I am honored by the trust patients place in me and feel privileged to help them cope with health-related issues. The field of medicine is constantly changing and demands continuous learning. That’s good for me and good for my patients.
