Why SIU?  I was fortunate to have the opportunity to work with the urology residents and faculty here at SIU while I was a medical student. I quickly realized they were the kind of people I wanted to train with for my residency.

Why SIU? In looking for a urology residency program, I not only wanted a great education and training, but a collegial environment that fostered mentorship in and out of the OR. Our program is a large extended family that offers ample research opportunities and surgical skills labs from the moment you start your residency.

Why SIU? When I came to visit SIU I was immediately struck by the comradery amongst the residents and attendings.  The residents are very close and hang out with each other outside of work.  It is also not uncommon to see attendings at our events.  The close-knit nature of the program fosters learning and has allowed me to grow as both a physician and person as a whole.  I'd like to believe the residents graduating from this program are some of the best in the country and can pursue both academic or private practice jobs and be successful.

Research Interest: prostate MRI, dual-energy CT, written two AUA updates (testosterone alternatives, complications of laparoscopy), written book chapters (urological surgical simulators, update on 5-alpha reductase inhibitors), current research interests in various endourological projects.

Why SIU? Here at SIU we truly are a family.  I did an away rotation here in medical school and couldn't get over how cohesive a team all the residents are with one another, both while working at the hospital and when we get together outside of work.  Also, family life is a priority here and everyone is very supportive of that. We also have a very diverse training atmosphere that includes rotation with the academic services as well as multiple private practice providers, so we see the entire scope of urology during residency. 



Bradley Holland, MD (PGY III)

Hometown Springfield, IL

Undergraduate Drake University, Des Moines, IA

Medical School: Southern Illinois University School of Medicine, Springfield, IL

Area of Interest: ALL of Urology

Research Interest: Rezum Procedure, Hypogonadism, Oncology

Why SIU? When looking for a residency program, finding a close knit group of faculty and residents was a large part of my decision. The camaraderie of SIU was evident immediately. Additionally, there is a devotion to education that is second to none. It is never more apparent than in dedicated Wednesday conference. SIU truly provides the best of both worlds. The experience and volume necessary to become a well-trained urologist ready for anything that comes through the ED, but also unique research and educational experiences required to obtain an elite fellowship position.


Robert Petrossian, MD (PGY II)

Hometown:  Los Angeles, California

Undergraduate:  University of California, Irvine

Medical School:  Oakland University William Beaumont School of Medicine

Area of interest:  Endourology and Stone Disease, Minimally Invasive (Robotic & Laparoscopic) Surgery​, Urologic Oncology, Prosthetics and Genitourinary Reconstruction, Men's Health

Why SIU? While rotating at SIU as a 4th year medical student, I was instantly drawn to the camaraderie and teamwork-driven mindset amongst the residents.  I was equally impressed with the surgical volume and exceptional level of hands-on experience the residents obtained in the operating room.  Now as a resident, I'm pleased to say my first impressions of SIU Urology remain true.  One intangible benefit worth noting is how close-knit the residents and faculty are with each other.  We spend plenty of time together both in and out the hospital, which effectively enhances the culture of our residency experience.  As someone who grew up around big cities, Springfield is a charming city that makes an ideal place to train with a low cost of living and close proximity to both hospitals we serve.  Simply put, SIU is not only a gem of the Midwest, but of the nation at large.

Why SIU? Coming from the West Coast, many thought it was odd that I applied here, but I received multiple recommendations for SIU from several attending surgeons at different programs. SIU has a​ reputation for training great urologists and surgeons in general and the program lives up to that reputation. Also, I love the small town feel and the family friendly environment while being centrally located between metropolitan areas like Chicago and St. Louis.
