John Tillett, MD, FACS, TUCC President

Former U.S. Navy Medical Corps Lieutenant Commander John Tillett, MD FACS, practiced urology in the military and also private practice in Florida before joining TUCC in 2016. He is currently an assistant professor at the University of Colorado School of Medicine. He is also is the director of the Urology training program for the Swedish Medical Center General Surgery residency program. He is also actively involved as a sub-investigator in multiple clinical trials in the TUCC Research Department.

Dr. Tillett graduated magna cum laude from Vanderbilt University and received his medical doctorate from Emory University School of Medicine, where he earned the Joseph B. Whitehead Surgery Scholarship. He completed his residency and served as Chief Resident at Emory, where he was recognized with the Department of Urology Award for Outstanding Academic Achievement and the prestigious Resident Achievement Award by the Society of Laparoendoscopic Surgeons. In 2010, Dr. Tillett was recognized by the Deputy Surgeon General of the U.S.Navy as being among the top five urology providers in the Navy ranked for satisfaction by outpatient clinic patients. He is certified by the American Board of Urology and is a fellow of the American College of Surgeons.

Dr. Tillett’s clinical areas of expertise include the management of chronic scrotal/testicular pain disorders, urinary stone disease, microsurgery, men’s health, bladder cancer, and urologic disorders in patients with spinal cord injury and other neurologic diseases. He has performed more microsurgical denervation of the spermatic cord operations for the treatment of chronic testicular pain than anyone in the region, and he was one of the first urologists in the country to specialize in the use of Jelmyto, an innovative, kidney-preserving treatment for urothelial cancers of the upper urinary tract.

In his free time, he enjoys spending time with his family, travel, tennis, and college football.
