About Aaron Gerds, MD

Dr. Aaron Gerds completed his undergraduate degree with honors (B.A. in biology and chemistry) at Hope College in Holland, Michigan. He then obtained his M.D. from Loyola University Chicago Stritch School of Medicine. Dr. Gerds stayed at Loyola University Hospital for his Internal Medicine residency training where he also served as chief resident. This is when he first became interested in hematology while analyzing the results of clinical trials under the mentorship of Dr. Patrick Stiff. This experience led him to pursue a master’s degree in clinical research methods and epidemiology during residency. Dr. Gerds then went to Seattle where he completed his hematology/oncology fellowship at the University of Washington, Fred Hutchinson Cancer Research Center. During his fellowship, he was awarded the ASBMT’s New Investigator Award. Under the mentorship of Drs. Joachim Deeg and Bart Scott, Dr. Gerds subspecialized in treating patients with myeloproliferative neoplasms (MPNs) such as polycythemia vera (PV), essential thrombocythemia (ET), myelofibrosis (MF), as well as myelodsyplastic syndromes (MDS) and chronic myelomonocytic leukemia (CMML), with a special emphasis on allogeneic hematopoietic cell transplantation. Dr. Gerds is also an active member of the American Society of Hematology, participating in both the Advocacy Leadership Institute and Clinical Research Training Institute, as well as serving on the Test Materials Development Committee. As Assistant Professor in Medicine (Hematology and Medical Oncology) at the Cleveland Clinic Taussig Cancer Institute, Dr. Gerds serves as the principle investigator for a number of clinical trials for the treatment of MPNs, and is focused on developing novel therapies for these patients.

Dr. Gerds is by far the best doctor I have seen for this situation. I am in the low risk category for this disorder, however, it is still a scary thing regardless of the risk level. Doctors in the past have not really given me the time to ask all of my questions or showed they cared about my fear of the situation because I am considered low risk. However, Dr. Gerd answered all of my questions and even took the time to find research to back up his responses which gave me an extra level of comfort. I am very happy to have him as my doctor for this now!
