About Us

At Weill Cornell Medicine, we provide comprehensive care for patients with cancer and blood disorders using a collaborative and multidisciplinary approach.

We care for the whole person and put the needs of our patients at the center of everything that we do. Our goal is to maximize patient outcomes and quality of life while minimizing thepotential side effects oftherapy. We think outside the box and listen to patients’ concerns and goals for treatment. World-renowned hematologists and medical oncologists work closely with specialized nurses, pharmacists, dietitians, social workers, laboratory scientists, and physicians from other disciplines — like surgery, pathology, diagnostic radiology, nuclear medicine, radiation oncology, psychiatry and pain management — to provide personalized care plans for each patient.

Our physicians — New York's leading hematologists and oncologists — use cutting-edge diagnostic methods and therapies,including precision medicine, to optimize results. Our diverse treatment options span immunotherapy, surgery, radiation therapy, chemotherapy, stem cell transplant, combination therapies and more.

Additionally, our physicians and scientists are actively developing and investigating new therapies. Through our more than 100 open clinical trials, we can offer access to many treatments that are not available elsewhere, including some of the newest and most innovative therapies in the field today.

I feel very cared for and comfortable with Dr Otterburn and his staff. Went through a double mastectomy and now getting ready for small revision. I was confused about what I should do. But my trust in the Dr is complete and his advice calmed my confusion and gave me confidence in what I needed to do. Best Dr ever.

Dr. Reeves took the time to talk with me about my case and explain in detail my particular situation. She was patient, kind and attentive to any questions I had, and from my discussion with her I feel very comfortable that she has a very high level of skill and professionalism. I had my visit on video and all worked seamlessly for a good and thorough appt.
