I am a medical oncologist and hematologist who cares for people with lymphoma, including Hodgkin lymphoma and non-Hodgkin lymphoma. I joined Memorial Sloan Kettering in 2008 and work as part of a team of experts who have chosen to dedicate their passion, knowledge, and experience to caring for people with lymphoma. I serve as Medical Director at MSK Bergen and am proud to be able to extend world-class cancer care to more New Jersey residents. I also see patients at MSK’s 64th Street Outpatient Center, in Manhattan.
Lymphomas are a group of diseases with tremendous variety. At the same time, the people who are diagnosed with lymphoma have very different lives, needs, and concerns. I work closely with each of my patients and their families to create a personalized care plan. That may include routine treatments, novel therapies, clinical trials, or autologous stem cell transplantation. My patients’ treatment depends on their diagnosis and what will most effectively treat their disease but also what fits into their lives and their goals. It’s my job to ensure that my patients receive the best treatments delivered in the best ways, but I am also here to be a partner and advocate, and to guide them through what can be a very difficult time.
My research is focused on finding new and better ways to treat lymphoma, specifically high-risk aggressive lymphomas and certain uncommon types of non-Hodgkin lymphoma. I am working to improve our understanding of how current treatments affect people in the long term so that we can develop better strategies to protect and preserve the health of our survivors after their treatment is over. Through my work and that of all the lymphoma experts at MSK, we are continuing to make great strides in how we care for people with these diseases.
Receiving a lymphoma diagnosis can be terrifying and isolating. The level of expertise at MSK, combined with exceptional support services, means people can be assured that they will receive excellent care, not only to treat their disease but also to help them through every step of their journey.
As a husband and father of three young children, I understand that people’s lives can be complicated, and I always work to understand who my patients are — and that they are far more than a diagnosis.
