About Me

I am a radiation oncologist who specializes in caring for people with breast cancer, primary and metastatic brain tumors, prostate cancer, bladder cancer, kidney cancer, and testicular cancer. I have expertise in using advanced radiation therapy techniques such as intensity-modulated radiation therapy, image-guided radiation therapy, stereotactic body radiation therapy, and stereotactic radiosurgery. I feel privileged to be able to help guide my patients through every aspect of their care, from diagnosis through treatment and into long-term follow-up. I see patients at Memorial Hospital in Manhattan, and at MSK Bergen, in New Jersey.

When I first meet with patients, my goal is to ensure they are informed and feel empowered. Thinking about a cancer diagnosis and what the future might hold can be daunting and overwhelming. Knowledge is one of the most important tools we have. I take time to teach my patients about the nature of their cancer and the advanced treatment options available so that we can begin to ease some of their concerns. From there, we work as a team to create the best treatment plan.

I also work closely with my colleagues in surgical and medical oncology to use the latest tools and knowledge to treat each patient. We are involved in every step of our patients’ care, so we really get to know them and their families. Because of these close relationships, we are able to take into account their needs and goals, in addition to being able to offer the most advanced, world-class care. Overall, this approach ensures that all patients receive a personalized and comprehensive strategy for treating their disease.  

I am involved in a number of clinical trials and laboratory-based studies. From the research we are conducting, we are learning that certain cancers may benefit from different regimens of radiation, while others may not require radiation at all. Discoveries about the underlying processes that drive cancer are increasingly allowing us to hone the precision with which we apply radiation, better targeting the tumor while sparing healthy tissue. Our ability to predict the effects of radiation on a personalized level is improving rapidly, and I am committed to bringing this cutting-edge research to my patients.

Clinical Trials

As home to one of the world’s top cancer research centers, Memorial Sloan Kettering is typically involved in more than 900 clinical trials at a given time. Currently, clinical trials focused on the conditions I treat are enrolling new patients.

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.
