I believe that effective medical care requires a comprehensive patient evaluation in a comfortable and friendly environment. I take the time to listen to my patients, making sure their needs are met and their concerns are addressed. I always try to explain medical complexities in understandable terms, and I work hard to ensure the best possible results. I am surrounded by staff and colleagues who share the same commitment. I'm excited to be part of a department that not only delivers excellent care, but also contributes to advances in endocrinology, diabetes and metabolism.
