Jason Lewis, DO, PA, FAAP
Pediatric Hematologist-Oncologist & Bone Marrow Transplant Specialist
My Role at MSKWe 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.

About Me
- Assistant Attending Pediatrician
I am a pediatric hematologic oncologist on the MSK Kids team who specializes in the care of cancerous and non-cancerous disorders of the blood and immune systems in children and young adults. In particular, I have treated patients with liver tumors (hepatoblastoma, hepatocellular, and hepatoblastoma mixed liver tumors), acute leukemias, germ cell tumors, Wilms tumor (a type of kidney cancer), sarcomas of the bones and soft tissues, neuroblastoma, Hodgkin and non-Hodgkin lymphomas, aplastic anemia, sickle cell disease, thalassemias, glucose-6-phosphate dehydrogenase (G6PD), hemophilia, and chronic neutropenia.
I chose this field because I enjoy working with young patients and getting to know their families. Having the chance to be a part of someone’s life during a time when they and their family members are in a vulnerable state is the most gratifying part of my job. I treat each patient and family member with respect and compassion to make their experience with us as gentle as it can be.
A pediatric hematologist-oncologist is a doctor who treats cancers of the blood in children and adolescents. This doctor is a hematologist (HEE-muh-TAH-loh-jist) who diagnoses and treats blood disorders. They also are an oncologist (cancer doctor).
A bone marrow transplant specialist is a doctor with special training in bone marrow transplants.
