Philosophy Of Care

First and foremost, my philosophy of care is centered on you as the patient. At the epicenter of your treatment experience, I want my patients and their families to know that I care about them and what happens with their health. Facing a cancer diagnosis can come with many challenges to the individual and those in their closest spheres. I want my patients to know that we will get through this together as a team. My goal is to incorporate a multi-disciplinary team approach to providing you a safe, seamless and personalized experience. I am here to guide you from diagnosis to the development of an effective treatment management plan and to monitor for possible alterations in quality of life along the way. I am committed to combining personalized medicine with current evidence-based strategies to treating your cancer with a focus of compassion, respect, autonomy and dignity.
