Roger A. Fleischman, MD, PhD

Section Chief, Hematology/Oncology, Lexington VA Hospital


My name is Roger A. Fleischman; I received my undergraduate and medical degrees from Harvard College and Harvard Medical School in Cambridge, Mass. After a medical residency at the Brigham and Women’s Hospital in Boston, I completed a fellowship in Hematology and Oncology at the University of Pennsylvania School of Medicine in Philadelphia. During the fellowship, I also engaged in basic research in the biology of blood and bone marrow stem cells at the Institute for Cancer Research at the Fox Chase Cancer Center in Philadelphia.

I accepted my first faculty position in Hematology/Oncology at the University of Texas Southwestern Medical School, Dallas in 1983 and served as a practicing clinician at Parkland Memorial Hospital in Dallas as well as a clinical and basic researcher into the molecular causes of bone marrow and stem cell disorders.

In 1993, I left Texas for the University of Kentucky and was appointed an Associate Professor of Internal Medicine in the Hematology/Oncology Division. As part of my duties at UK HealthCare, I also serve as Chief of the Hematology/Oncology Section at the Lexington VA Hospital. At UK HealthCare, I see patients primarily with lymphoma, leukemia, and other bone marrow disorders.

I have published many research papers and abstracts and my research has been presented at numerous meetings both national and international. I was also recently recognized by the Hematology/Oncology fellows for outstanding teaching. I received 2015 designation as a Distinguished Emeritus Member by the American Society of Hematology for “exemplary service and efforts in the advancement of the field of hematology”. I am married to Dr. Elizabeth Piercy, an Infectious Disease specialist in private practice in Lexington and we have two daughters.
