General Info

About me

Since always, I wanted to be a surgeon. When I learned about surgical oncology, I saw it as challenge and opportunity to support people and to help separate the word “cancer” from “death”. What I like the most about being a surgical oncologist is that each patient is a new experience because every surgery is unique and different. Every patient has an opportunity to survive and it is my goal to help. As of 2013, I have more than 15 years of experience. I work full time at my Surgical Oncology private practice where we focus on: thyroid surgery, breast pathology, gastric cancer and colorectal cancer.
