Philosophy of care | Personalized care starts during my first meeting with a patient and family. That's when I get to know the patient as completely as possible. I want to know about the patient's concerns, values and support system so I can provide care that is specific to him or her. | Also, I am a member of the skin and soft tissue cancer multidisciplinary consultation team. Together we review your diagnostic information and give you a written opinion reflecting the scope of your condition and recommendations for your best course of care. | Why I entered medicine | When I was young, I didn't like seeing doctors. It created a lot of anxiety for me. Now that I'm older, I can relate to the way people feel, especially when they're coping with the emotions caused by a serious condition like cancer. My grandmother died of uterine cancer in the 1960s. During her battle, I felt helpless. That is what attracted me to cancer research. Now I see the amazing progress we are making through cancer research. | Community involvement | I served on the state board of the American Cancer Society. Today, I take more of a grassroots approach to offer my support. I participate in events, such as 5K runs, that benefit charities.
