Michael B Maris, MD

Dr. Maris specializes in the treatment of patients with blood cancers as well as expertise in the use of blood and marrow transplantation for hematologic malignancies. He is the Research Director for the Colorado Blood and Marrow Transplant Program at the Colorado Blood Cancer Institute. He received his medical degree from the University of Pennsylvania and he completed his internal medicine residency at the Oregon Health Sciences University in Portland, Oregon. Dr. Maris completed his Oncology and Blood and Marrow Transplantation Fellowship at the Fred Hutchinson Cancer Research Center/University of Washington in Seattle, Washington. His research focus at that time was expanding the role of allogeneic transplantation to older and infirm patients through the use of nonmyeloablative allogeneic hematopoietic stem cell transplantation. Dr. Maris has published extensively in this area. His current research interests are in further optimizing allogeneic hematopoietic transplantation for patients of all types as well as the development of novel drug and drug regimens for the treatment of the patients with acute myeloid leukemia. Dr. Maris has extensive experience as an investigator in multiple clinical trials and he has expertise in the treatment of patients with acute myeloid leukemia and aggressive lymphomas.
Care Philosophy

I believe that physicians are educator/guides during the cancer treatment process and patients should be empowered with the knowledge to guide their decisions. Patient understanding of the underlying disease process and therapeutic options is a requirement in the shared clinical decision making between the patient and his/her physician.
