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.

Surgery
I am a board-certified surgeon who specializes in caring for people with endocrine tumors and sarcoma, including gastrointestinal stromal tumors. These include diseases of the parathyroid, thyroid, adrenal glands, and the gastrointestinal tract. Because these conditions are often complex, I work closely with colleagues in endocrinology, medical oncology, radiology, gastroenterology, and pathology to deliver state-of-the-art multidisciplinary care. Our team of physicians and nurses works tirelessly to deliver the best possible medical, surgical, and follow-up care. Sometimes multiple treatments can exist for these conditions. It’s critical that patients have an in-depth understanding of their options. If surgery is necessary, our team will answer questions and explain what patients might anticipate leading up to and after surgery.

Recovery after surgery can be difficult, which is why I I use minimally invasive surgical approaches whenever possible. With these techniques, patients have less pain and can recover faster than they otherwise would. Sometimes minimally invasive approaches cannot be used. In these instances, I work closely with my anesthesia colleagues to provide the most comfortable experience possible.
My research, which is part of the Human Oncology and Pathogensis Program, focuses on mechanisms of thyroid and gastrointestinal tumor progression and responses to therapy. Using genetically accurate models of cancer, we explore why certain tumors are more aggressive than others and how best to treat these with various interventions. For this work, I have been awarded multiple grants including those from the American Surgical Association, the American Thyroid Association, the American Association of Endocrine Surgeons, and the North American Neuroendocrine Tumor Society.I have also lectured on endocrine and gastrointestinal surgery topics all over the country and have published numerous articles on how best to care for patients.
Improving the quality of care patients receive is my top priority. After getting a diagnosis, patients can have a lot of anxiety about next steps. My role is to help patients through this and get them the best possible treatment.
Our team of physicians and nurses works tirelessly to deliver the best possible medical, surgical, and follow-up care.
