Brent Keith Hollenbeck MD



Brent K. Hollenbeck, M.D., M.S. is a practicing urologic oncologist and has been on faculty at the University of Michigan since 2003. A graduate of the Indiana University School of Medicine, Dr. Hollenbeck completed his residency in urology and fellowship training in oncology at the University of Michigan. During the past 5 years, his clinical practice has grown in patient volume, which complements his research imperative. Over this time, he has become increasingly specialized in the care of patients with prostate and bladder cancers. This focus has afforded him the ability to maintain his commitment to research while continuing to deliver cutting-edge, high quality care.

Dr. Hollenbeck is currently an Associate Professor of Urology and the Director of the Herbert H. and Grace A. Dow Division of Health Services Research at the University of Michigan. He is firmly committed to training the future leaders in urologic health services research. Further, he strongly believes that populating the surgical specialties with health services researchers will yield long-term benefits to both our specialty and our patients.

When he is not engaged in clinical and research pursuits, Brent is a very active swimmer, runner and fly fisherman (especially for steelhead). Perhaps most importantly, however, he enjoys spending the bulk of his free time with his wife and two daughters. The Hollenbecks are avid fans of Michigan athletics and look forward to cheering on the Wolverines on football Saturdays.

During his fellowship training, Dr. Hollenbeck completed a Masters of Science program in research and design and biostatistics at the University of Michigan's School of Public Health. His research interests are policy-oriented and are focused squarely on understanding the upstream influences and downstream consequences of variation in physician practice style. His current initiatives include measuring effects of physician financial incentives and identifying best practices for early stage bladder cancer. The former consists of a 4-year R01, from the Agency for Healthcare Research and Quality, to better understand relationships between ambulatory surgery centers and outpatient surgery use. The latter is part of a 5-year award, funded by the American Cancer Society, using alternative statistical methods (e.g., instrumental variables analysis) to make inference from observation data.
