Dr. Badger earned a Bachelor of Science in chemistry at Hobart and William Smith Colleges. Chemistry was fascinating, but he needed more personal interactions, and medicine seemed to be a great combination. After being accepted into medical school, he along with his future wife, Sarah, elected to defer medical school for a year to make sure that they were a good match for each other and that medicine was his ideal career. Fortunately, both medicine and Sarah have been great matches, and Hawaii was a pretty cool place to spend a year. They both became die-hard Buckeyes while Dr. Badger was in medical school at Ohio State University and Sarah was earning her degree in Occupational Therapy. After completing his residency in Urology at Albany Medical Center, he completed a Fellowship at the University of Iowa in Endourology, Laparoscopy, and Robotics.

Dr. Badger and his wife moved to Flagstaff, Arizona, in 2009 with their three awesome girls. They’ve found a great community here and love the many activities and adventures that Flagstaff and Northern Arizona have to offer. They have tried to add back to the community in many ways, not only by being a part of the fantastic medical community. They support their local public schools, which their children attend, as well as many local organizations and nonprofits. Dr. Badger sits on many committees at Flagstaff Medical Center, and he is Chairman of PathfinderHealth ACO, which is working to transform healthcare to deliver excellent medical care for all members of the community in a sustainable fashion.

As for Urology, Dr. Badger strives to provide excellent, compassionate, and state of the art care. He introduced robotic and laparoscopic renal and prostate surgery to Northern Arizona. He utilizes advanced technology when possible from electronic medical records to advanced imaging and in-office procedures. Dr. Badger treats all genders and ages for most urologic conditions.
