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.

I have already recommended Dr. Gerds and the Cleveland Clinic to dozens of patients through various forums and I will continue to do so. I've had a pretty good exposure to world class treatment centers around the USA and some of the top doctors... and I would put Dr. Gerds right there with any of them. We were discussing the fact that I have progressed (regressed?) from an intermediate risk level to a high risk level with a terrible 5 year outlook. It is tough stuff, but Dr. Gerds hit just the right tone...

Dr. Gerds is very professional, respectful and patient. He is always willing to answer any questions that I have. His explanations are always in terms to understand the science behind my disease. I will always recommend Dr. Gerds to others. My wife & I look forward to our visit with Dr. Gerds.

Dr. Gerds is an exceptional physician. He begins every office visit by asking me how I am doing. And, he listens to what I am saying. He explains all testing results in terms I can understand. He truly cares about his patients and makes you feel at ease even when the information he is providing is not positive. He is very compassionate.

I truly cannot say how impressed I have been with my experience at Cleveland Clinic in general and with Dr. Gerds, in particular. As a physician, he is second to none. From my first visit, he took all the time necessary to talk with me and address my concerns. He is extremely informed about the rare blood cancer with which I have been afflicted and spends time acquiring information about latest research and treatments. I am willing to travel 3 1/2 hours to see him, following a truly terrible experience at OSU James Cancer Hospital. I frequently share his name and my experiences on a Facebook page to which I belong solely for individuals with my blood disorder. I am so thankful for Dr. Gerds, the staff at CC, and the facility, in general. I feel I would not be doing as well as I am without the care and support I receive at Cleveland Clinic.

It was very frustrating. Last April, I was trying to set up a bone marrow biopsy with radiology. I was told that I needed a separate approval from my insurance for the bmb and when trying to contact the right department to see if it was handled or not, no one seemed to know who was responsible. I was put through to several different departments, put on hold, and disconnected frequently. This had nothing to do with Dr. Gerds department, but more with the rest of the network
