Philosophy of Care

A cancer diagnosis is a life-altering event for not only the patient but their whole family. My role is to partner with you to do everything possible to achieve your goals. At all times, I try to follow the guiding principle of providing the kind of care I would give to my own family member. I am passionate about cancer research because we should all expect and demand better treatments and higher cure rates.
