We post reviews for MSK healthcare providers who have at least 30 patient experience surveys completed. If you do not see reviews for a provider, it may be because they do not yet have enough survey responses, or the provider may not be part of the group of healthcare providers included in the survey.
Only outpatient providers are included in the survey. Healthcare providers who only work in the hospital or in urgent care are not included in the survey. Pathologists or researchers who do not provide direct care to patients do not have reviews.

Radiation Oncology
I am a radiation oncologist who joined the faculty of Memorial Sloan Kettering more than a decade ago. While over the years I have treated a wide variety of cancers, I have developed an expertise in brain tumors (primary brain tumors and brain metastases), gastrointestinal cancers (esophagus, stomach, colorectal, anal, pancreas, liver, and biliary), breast cancer, and metastatic disease (bone metastases, including spine metastases).
I had the good fortune to be part of the team that opened MSK Westchester, where I now see more than 500 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 routinely deliver stereotactic radiosurgery for brain tumors, ablative dose radiotherapy for pancreas and liver cancers, and stereotactic body radiotherapy for bone and spine metastases. 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.
I take pride in maximizing my relationships with my world-class colleagues to deliver an integrated team approach.
