Treatment Philosophy

I take an evidence based, patient centered approach to your evaluation and treatment. Each consultation will begin with listening to your questions and concerns, and a thorough medical history, physical examination, and review of any available imaging. Together we will decide on the best treatment course within the framework of evidence based gold standard medical care. I treat every patient with the same care and compassion that I would expect for myself and my family.

    She is the most wonderful and caring doctor. Listens, explains and interested in all aspects of my recovery. She does everything possible for me as her patient and I know she truly cares about my health and well being. I feel very lucky that I was able to have her as my surgeon for a major cancer surgery.

    was misinformed of having a "tumor" and referred to this dr. She reviewed all medical records, and concluded there was no tumor. She is definitely an one of the better doctors I have visited. Her bedside manner was perfect. I appreciate her taking the time to listen and review all the facts before making a diagnosis.
