Meet Our Team


Dr. Jimmy Xu

Dr. Jimmy Xu is from Fayetteville, Arkansas, and completed his bachelor of science in industrial engineering at University of Arkansas. He completed his medical degree at the University of Arkansas for Medical Sciences and his general surgery training at St. Louis University. Finally, he underwent further training in a Minimally Invasive, Bariatric, and Robotic Surgery fellowship in the Bay Area of Oakland, California. This extra training was to offer patients more options in terms of minimally invasive surgery and ultimately faster and less painful recovery.

Dr. Xu has a special interest in weight loss surgery as well as upper gastrointestinal surgery using a variety of minimally invasive techniques. He completed his fellowship in robotic surgery as well and completed more robotic cases than any fellow in California.

After fellowship, he moved to Henderson, Nevada, and helped grow the robotic surgery program at St. Rose Dominican’s Siena Campus and became the medical director of weight loss surgery there. Throughout Dr. Xu’s extensive training and accomplishments, his guiding quote has been, “I ask not for a lighter burden, but broader shoulders.”


Dr. Mustafa Ahmed

Dr. Mustafa Ahmed is a board-certified bariatric surgeon in Las Vegas. He has more than 20 years of experience helping patients achieve their dreams of improved health and self-esteem. He believes that a person’s most prized possession is their health and works hard every day to help his patients achieve happiness via healthy lifestyle changes.

Dr. Ahmed attended Ohio State University in Columbus, Ohio, for his medical education. After graduating in 1996, he completed an internal medicine residency with Mount Carmel Medical Center.

After completing six years as an internist, Dr. Ahmed changed direction in his career and became a bariatric surgeon. During those six years, he often treated patients for obesity-related conditions like high blood pressure, osteoarthritis, and coronary artery disease. He also saw his patients’ frustrations as they attempted weight loss and remission of their conditions to no avail. He finished a general surgery residency at Morehouse School of Medicine in Atlanta, and later, he completed fellowships in surgical critical care and his current specialty, bariatric surgery.
