Care Philosophy

We are not a "factory" or a "machine", moving patients through as if they are boxes in a warehouse. Instead we provide personalized and compassionate care that is state of the art.  We take the time to get to know our patients, and partner with them to devise the best available evaluation and treatment program.  While we are well aware of "guidelines", "treatment algorithms", and "institutional programs and regimens", we focus on what is best for the individual patient rather than a cookbook.

Patients seek treatment here because they are referred here by their physicians, who recognize our expertise and know that across the region and the country we are a "go to" place to seek the best lymphoma care.  Our physicians are internationally recognized for clinical skill, research, and personal qualities.  In fact, we care for a substantial number of individual physicians (or their family members) who are themselves dealing with lymphoma.  

Cancer patients don't always (or unfortunately won't always) just have cancer - they have multiple other complex medical problems that may be active concurrently with or exacerbated by cancer treatment.  Weill Cornell Medical College physicians are among the best across all medical specialties, not just cancer.  New York Presbyterian Hospital is one of the top hospitals in the nation.  This can be particularly valuable in patients dealing with issues such as cardiology, pediatrics, obstetrics and gynecology, neurology, endocrinology, lung and kidney issues.  Patients do not want to have to be sent to another hospital or center should their other medical issues become a problem in the midst of cancer treatment.  They want access to the best specialists if needed, all in one place, in a coordinated fashion.  

Our center provides access to the full array of resources needed for "comprehensive" cancer care.  This includes nutrition, psychosocial support, complementary medicine, rehabilitation, pain management, and other areas.  We have developed an outstanding team of physicians (including medical oncologists, radiation oncologists, pathologists, and others), nurses, physician assistants and related health care personnel in order to optimally serve patients with these disorders.  Our patients recognize the value of this support.
