Radiation Oncology

I am a radiation oncologist who joined the faculty of Memorial Sloan Kettering more than a decade ago. While I treat a wide variety of cancers, I have developed an expertise in gastrointestinal cancers, brain tumors, breast cancer, and prostate cancer. I had the good fortune to be part of the team that opened MSK Westchester, where I now see more than 300 new patients a year.

I discovered radiation oncology during my final year of medical school. This field of medicine allows me to be part of my patients’ inspiring journeys while also solving complex medical and physics problems.  

I am particularly skilled in cutting-edge treatments including intensity-modulated radiation therapy and image-guided radiation therapy. These advanced radiation techniques allow us to deliver more-accurate treatments while protecting adjacent organs, thereby improving results and reducing side effects. I am part of a team that routinely delivers stereotactic radiosurgery for brain tumors and hypofractionated radiotherapy for prostate cancer. One of the privileges of working at MSK is being part of our research team and offering national and institutional clinical trials to patients. I take pride in maximizing my relationships with my world-class colleagues to deliver an integrated team approach.

Our Westchester facility is a unique place. What makes it so special is the breadth of MSK departmental services offered and the professional relationships and friendships I have made, which ultimately benefit my patients.

My goal with all my patients is to clearly explain their disease and treatment while also making them feel well cared for, both medically and personally. 

Outside of the hospital, I love trying new sports, baking desserts, and most of all spending time with my family.

I take pride in maximizing my relationships with my world-class colleagues to deliver an integrated team approach.
