About Me

I am a radiation oncologist who specializes in caring for people with prostate, breast, gastrointestinal, and gynecologic cancers as well as brain tumors. I am part of a team of medical oncologists, medical physicists, surgeons, and radiologists who provide state-of-the-art, compassionate care to patients at Memorial Sloan Kettering Basking Ridge. I see about 300 patients each year.

I always knew I wanted to become a doctor, but it wasn’t until my mom was diagnosed with cancer during my freshman year of college that I became interested in oncology. When she underwent treatment at MSK, I realized I wanted to be just like the doctors taking care of her. Her excellent radiation oncologist particularly inspired me.

I love working at MSK Basking Ridge because we offer the most advanced treatments in a warm, nurturing environment close to home. I have a particular interest in the use of imaging techniques that deliver highly focused radiation to cancerous tissue and reduce damage to normal tissue. These include intensity-modulated radiation therapy and image-guided radiation therapy. I also use high-dose-rate brachytherapy (radiation delivered by a radioactive source placed directly in the tumor) to treat patients with gynecologic tumors who would benefit from this approach.

I am interested in enrolling patients in clinical trials at MSK Basking Ridge to help find new approaches to treating cancer. I can also help patients gain entry into trials that are available at MSK in Manhattan, if appropriate.

Sometimes patients are nervous about starting radiation treatment. I try to reassure them that even though they have never done this before, I have guided hundreds of other people through this process. I think of myself as a partner in their treatment and am here to educate and empower them.

Outside of work, I love spending time with my three children, reading, and playing tennis.

Most major health insurers offer plans that include MSK as one of their in-network providers. If MSK is in-network, it means all our doctors are too. Medicaid and New York State Medicare also provide benefits for care at MSK.
