Retiring Faculty, 2018-2019

Over the last year 10 faculty members within Internal Medicine have retired or are about to retire at the end of this academic year. We asked each faculty member’s Division Director to speak briefly about their impact on the department and on the Carver College of Medicine. We are grateful for their contributions.

Dr. Allyn Mark has served this institution for 50 years and has transformed not only the college, the department, and this division, but every physician’s understanding of hypertension and obesity as well. As accomplished an investigator as he is, his true passion has been in education, earning the university’s Distinguished Mentor Award in 2013. He has served in many leadership roles, including directing this division, as Associate Dean for Research, and as Co-Founding Director of the UI Obesity Research and Education Initiative. His influence and impact over the decades can be seen in almost every corner of the work we do today. He continues his efforts to strengthen the university’s weight management program by working closely with the recruitment of providers and providing input in clinic operations.


O'Dorisio,ThomasThomas O’Dorisio, MD

E. Dale Abel, MD, PhD, Director of the Division of Endocrinology and Metabolism
Tom’s passion for patients with neuroendocrine tumors (NETs) is responsible in part for developing one of the largest referral practices for NETs in the United States, which recently received a Center of Excellence designation – the only such recognized program in the United States. Tom has been devoted to his patients, who think the world of him, in terms of his attention to all their clinical needs and to supporting them through complex therapeutic regimes. When he attended on the consult service, Endocrine fellows were “well-fed.” Thanks for the hundreds of bagels over the years, Tom, that sustained our trainees!

Dr. Rachow was a dedicated and compassionate geriatrics physician with additional training in Rheumatology who spent his career traveling thousands of miles throughout Eastern Iowa to provide primary care to patients residing in rural nursing homes.

These include serving as Division Director, and also in leading the Endocrine section at the Iowa City VA. In addition to being an active clinician and a committed teacher for our Endocrine Fellows, Bill was also an accomplished basic and clinical investigator. He made seminal contributions to our understanding of the contribution of mitochondrial energetics to diabetes and its complications.

His impact stretches far beyond our institution and it has been an honor to work alongside him. He has extensive plans for an enjoyable retirement and I enviously wish him the best!
