Brian Prebil, DO
Brian Prebil, DO, is a board-certified general surgeon leading the team at the Center for Minimally Invasive and Robotic Surgery in Peoria, Arizona.
A graduate of Western University of Health Sciences in Southern California, he completed his surgical internship and general surgery residency at Maricopa Medical Center in Phoenix, Arizona. Upon completion of his surgical training, he entered private practice and has been in practice for 16 years. He is board-certified by the American Board of Surgery. Dr. Prebil served as the Chairman of Surgery at Banner Thunderbird Medical Center on three separate occasions and was the Surgical representative for Banner Surgicenter for 10 consecutive years.
Dr. Prebil was trained on the da VinciⓇ robotic surgical system in 2012. He is one of the most experienced robotic general surgeons in the United States and has done almost 2000 robotic general surgery cases. Along with his peers at the Center for Minimally Invasive and Robotic Surgery/Hernia Center of Arizona, he has developed many of the robotic surgical techniques used by national and international surgeons. He is co-director of CMIRS/HCA and runs one of the few da Vinci Robotic General Surgery Epicenters in the United States.
Believing that robotic surgery changes the scope of surgery for the patient and the surgeon, Dr. Prebil shares that the da Vinci robotic surgical system “allows surgery that was once limited to an open procedure to be done minimally invasive, with better precision, better technique, less pain, and faster patient recovery.” This leads to a better patient experience and a quicker return to work and life.
With a commitment to educate and pass on surgical knowledge and techniques to upcoming practitioners, Dr. Prebil serves as a Faculty Member/Attending Surgeon at the Creighton University School of Medicine/Maricopa Medical Center General Surgery Residency Training program and Core Faculty at the Abrazo Healthcare Network Surgery Residency Program. He educates medical students as an Associate Clinical Professor of Surgery at Midwestern University Medical School.
As a consultant with Intuitive Surgical and Bard Medical, he hosts and educates national and international surgeons in case observations, hernia courses and proctoring surgeons in surgical techniques developed at CMIRS/HCA. He is also an Attending Staff Surgeon at the Phoenix VA Healthcare System, giving back to America’s Veterans.
Outside of his surgical practice, Dr. Prebil is a dedicated husband, and father to three wonderful children. He stays active with Ironman Triathlons, skiing, and traveling.
Rachel Alt, MD
A board-certified general surgeon, Rachel Alt, MD, graduated from the University of Missouri School of Medicine in Columbia, Missouri in 2012. After medical school she moved to Arizona to complete her surgical training at Maricopa Medical Center in Phoenix. During this time she had the opportunity to train under Dr. Prebil and surgeons at CMIRS and was introduced to the DaVinci Xi robotic platform.
After witnessing the benefits of robotic surgery first hand, Dr. Alt decided to pursue additional training in robotic surgery. She completed an accredited 1 year fellowship at The Valley Hospital in Ridgewood, New Jersey. Her training focused on laparoscopic and robotic hernia repair and anti-reflux surgery. During this time she performed over 500 surgeries, including 300 robotic cases.
Dr. Alt was also involved in clinical research during fellowship. Alongside her mentor, she conducted several studies that examined the outcomes of robotic surgery with the goal of minimizing post-operative pain and improving quality of life. These studies were presented at the Society of American Gastrointestinal and Endoscopic Surgeons meeting in 2019, and are in peer review for publication.
After gaining extensive hands on robotic experience in fellowship, Dr. Alt returned to Phoenix to join the team at CMIRS.
Outside of her clinical practice, Dr. Alt enjoys hiking, camping with her husband and son, and visiting her home state of Iowa.
Jarvis Walters, DO
Dr. Walters and his wife were born and raised in Oklahoma. He attended the University of Oklahoma where he completed a B.S. in Civil Engineering. Dr. Walters then moved to the Phoenix metro area where he earned his medical degree at the Arizona College of Osteopathic Medicine and completed his general surgery residency at Maricopa Medical Center.
He then completed a surgical fellowship in Advanced Gastrointestinal and Minimally Invasive Surgery at George Washington University Hospital and the Washington DC VA medical centers. During this time, he received additional training in advanced laparoscopic and robotic procedures of the esophagus, stomach, pancreas, colon, and abdominal wall and performed numerous minimally invasive procedures including hernia repairs, advanced endoscopy, and oncologic operations to remove cancers.
Following training, Dr. Walters joined a Wichita, KS-based full-spectrum general surgery practice with a heavy focus on EGD/colonoscopy, hernia repairs, anti-reflux procedures, and colorectal surgery. He now returns “home” to Phoenix with his family to establish roots.
Dr. Walters is married with three children who were all born in Phoenix. He enjoys playing golf, attending sporting events, and coaching his kids’ athletics
