Why a patient should choose treatment at your practice?

My approach to cancer care is that we are a team of professionals and our goal is taking the best care of you, the patient. We have a holistic approach to cancer care and make sure the patient and the family are involved in all the treatment decisions and truly understand the plan of care.

What is your personal philosophy around patient care?

We are gaining new scientific information everyday regarding cancer and my job is to master the data and techniques to offer the most cutting edge technology, but also make sure the patient and family understand that we are all on the same team and will fight this disease together.

Why did you become a doctor?

I became a doctor because it was the one skill that I felt I could learn and be useful to the most amount of people anywhere in the world.
