Scott Castle, MD

Scott Castle, MD is a board-certified urologist at Valley View’s Rocky Mountain Urology Center. He received his medical degree at the University of Tennessee College of Medicine and completed his urology residency at Jackson Memorial Hospital, affiliated with the University of Miami School of Medicine. Prior to joining the Valley View family, Dr. Castle practiced in Columbia, SC where he was an assistant professor of surgery at the South Carolina College of Medicine. He is published in multiple peer-reviewed journals and has conducted a number of clinical trials throughout his career.

Dr. Castle is a general urologist with vast experience treating all urologic conditions including kidney stones, incontinence, bladder and kidney cancer, and men’s health issues. He is also a leader in da Vinci surgery, a minimally-invasive treatment for benign and cancerous conditions. The procedure is named for the da Vinci robotic system, which lets surgeons use their hand movements to control tiny instruments in real time. This treatment option can often give patients better quality of life post-surgery, particularly in terms of urinary function and sexual health for treatment of prostate cancer.

When it comes to his patients, Dr. Castle prioritizes his relationships. “I have a history of cancer in my family, which informs the way I do my job today,” he says. “I create bonds with my patients so I can give them the same empathy and personalized treatment I wanted for my own family members.”

Dr. Castle and his wife have two children, and physical activity is a big pastime for all of them. He is a former Ironman athlete, and these days, enjoys spending time outdoors with his family, happy to be in the mountains with easy access to skiing and other wintertime activities.

Stephen Williams, MD

Stephen Williams, MD, is the newest member of Valley View’s Rocky Mountain Urology Center. Dr. Williams is a urologist who is specially trained in urologic oncology. He is thrilled to be a member of our medical community.

Dr. Williams was born and raised in Philadelphia, Pennsylvania (and remains an avid Philadelphia sports fan). After completing his undergraduate degree from Princeton University, he attended medical school at Loyola University’s Stritch School of Medicine in Chicago, Illinois. Dr. Williams went on to the University of California, Davis School of Medicine to complete a six-year urology residency program. Dr. Williams additionally completed a two-year fellowship program at the University of Southern California, Norris Comprehensive Cancer Center in Los Angeles, where he specialized in the surgical treatments of urologic cancers. He has since built his career of 22 years providing care for patients with prostate, bladder, testicular and kidney cancers, in addition to other general urology concerns.

Dr. Williams has previously been on the faculty of several medical institutions and served in leadership roles both in northern and southern California. Prior to joining Valley View, he spent 10 years as director of urologic oncology for the Southern California Permanente Medical Group.

Dr. Williams and his wife, Lori, have recently relocated from southern California to the Roaring Fork Valley. While they have only been here for a short amount of time, they are already feeling at home and are thrilled to be living in such a beautiful, perfectly sized and caring community. “We’ve met so many incredibly nice people both at Valley View and in the community at large.”

Dr. William’s philosophy of care involves creating long-term and rewarding relationships with his patients. “I love urology because we are involved in the entire spectrum of patient care,” he says. “We establish the diagnosis, and are then able to offer an array of treatments – both medical and surgical -and provide all of the follow up care. In the case of patients diagnosed with cancer, their post-treatment care can last years, so we really get to know our patients along their journey.”

Dr. Williams is a former collegiate athlete and exercise continues to remain a high priority in his life. What better place to live, in which this balance of life can exist! He especially loves to golf, play tennis, hike, ski, practice yoga and play and listen to music (he’s known to play music in the operating room to create a comfortable environment for his patients and staff, with patient permission, of course). He and his wife look forward to becoming active members of the community, while once again enjoying the beauty and appeal of living among the four seasons.
