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.

Get to Know Me
I am a practicing radiation oncologist with a focus on clinical trials for genitourinary cancer, which includes prostate cancer, bladder cancer, and kidney cancer.
My goal is to use the latest imaging and radiotherapy technologies to improve treatment results for patients. I see patients at Memorial Hospital and the David H. Koch Center for Cancer Care at MSK.
Recent advancements in radiotherapy have improved our ability to precisely target tumors, so that treatments are now effective as well as minimally invasive. The use of real-time imaging and adaptive treatment planning also plays an important role in delivering personalized care. I believe that every person deserves a treatment plan tailored to their unique needs and situations. I emphasize precision and adaptability in radiation therapy. This approach not only enhances the treatment results but also reduces side effects, which improves the patient experience.
When patients first meet with me, they often express concerns about the safety and effectiveness of new treatment technologies. I take the time to thoroughly explain the procedures and benefits, making sure that they feel informed and confident in their treatment plan. My goal is to provide the latest care in a warm and supportive environment.
I also serve as the Director of the Genitourinary Program in the Department of Radiation Oncology. In this role, I oversee the development and use of the latest treatments and clinical trials so that our team is a leader in radiation therapy.
I'm a radiation oncologist, which is a cancer doctor with special training in using radiation therapy (RT) to treat cancer.

Disclosures
Members of the MSK Community often work with pharmaceutical, device, biotechnology, and life sciences companies, and other organizations outside of MSK, to find safe and effective cancer treatments, to improve patient care, and to educate the health care community. These activities outside of MSK further our mission, provide productive collaborations, and promote the practical application of scientific discoveries.
MSK requires doctors, faculty members, and leaders to report (“disclose”) the relationships and financial interests they have with external entities. As a commitment to transparency with our community, we make that information available to the public. Not all disclosed interests and relationships present conflicts of interest. MSK reviews all disclosed interests and relationships to assess whether a conflict of interest exists and whether formal COI management is needed.
