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.

I am a member of the MSK Kids team who specializes in the care of children and young adults with blood (hematologic) cancers, including leukemias and lymphomas. I specialize in the treatment of Hodgkin lymphoma that has come back (relapsed) after prior therapy. I also care for patients with histiocytic disorders, including Langerhans cell histiocytosis.
In addition to caring for patients, I am conducting research to develop and assess better treatments. My research focuses on the development of novel therapies and treatment approaches for patients with lymphoma, with aim to improve their outcomes and minimize long-term side effects. I am MSK’s institutional Principal Investigator for the Children’s Oncology Group, the nation’s largest collaborative clinical research organization focused on childhood cancers.
When I meet a patient and family, I approach them with honesty, regardless of their age. I emphasize that this journey is something we are embarking on together. I thoroughly review their treatment options, emphasizing how the therapies we now have for their cancer have evolved.
I chose this field because as a physician, I can be on the cutting-edge of exciting technologies and emerging therapies. I am able to develop strong bonds with our patients and their families through difficult times, which often last for years. I support children and young adults as they battle through the worst times of their lives and am enormously gratified when I am able to watch them develop into healthy and successful adults.
