Rocky Mountain Pediatric Surgery was founded in 1991 by Dr. Jack Chang. A prominent university-based pediatric surgeon, Dr. Chang wanted to deliver more customized, personal care. Within a few years, his practice was rapidly expanding and he was joined by Denver native Dr. Steve Rothenberg. Dr. Rothenberg and Dr. Chang began their pioneering work in minimally invasive surgery in children during the 1990's, basing the majority of their work at Presbyterian/St. Luke's Hospital, but also treating children at the Children's Hospital, and at several Denver area hospitals. Drs Chang and Rothenberg laid the foundations of the unique brand surgical care that the practice now provides including: Custom service that is faster and easier than usually available. Revolutionary new techniques to minimize pain, scarring, and risk in all operations. Access to expert pediatric surgical care anywhere in the Denver area. The practice thrived. Soon, referrals arrived not just from Colorado, but from the entire mountain region, and even the rest of the country. RMPS now accepts local, regional, national and international referrals. As the practice grew, Dr. Saundra Kay joined in 2003, and Dr. Kristin Shipman in 2008.
