M. Jonathan Worsey, MD, is a board-certified colon and rectal surgeon at San Diego Colon and Rectal Surgeons in La Jolla, California. Dr. Worsey was born in South Wales and obtained his undergraduate degree from the prestigious University of Cambridge, England, being the first person in his family to attend college. He studied medicine at St. Thomas’ Hospital in London, which can trace its origins as a place of healing back to the 12th century, obtaining his medical degree in 1985 with honors. Following junior surgical residency positions in the United Kingdom, he came to the United States in 1989 on a two-year research fellowship at the University of Iowa.
From 1991-1997, he was a surgical resident at the University of Pittsburgh Medical Center and during his time in research there, was awarded an American Heart Association Fellowship. In 1997, he began a fellowship in colon and rectal surgery at the Cleveland Clinic, Ohio, which is among the most respected training programs in the world in this specialty. He then remained for an additional and invaluable year at the Cleveland Clinic, working directly under world-renowned colon and rectal surgeon, Dr. Victor Fazio, a pioneer in this field and a master surgeon and clinician.
In 1999, Dr. Worsey moved to La Jolla, California, to enter practice with Dr. Dana Launer, another Cleveland Clinic-trained colon and rectal surgeon. Sadly, Dr. Launer died in 2010, and in 2013, Dr. Beiermeister joined the practice.
Dr. Worsey has board certifications in general surgery and colon and rectal surgery as well as being a fellow of the Royal College of Surgeons (England), the American College of Surgeons, and the American Society of Colon and Rectal Surgery. He has been Chief of both General Surgery and Surgery at Scripps Memorial Hospital in La Jolla and in 2014-2015 was Chief of Staff. He also currently holds a part-time position as Physician Chief Operating Executive at Scripps Memorial Hospital, La Jolla.
Additional accolades include numerous awards for scientific presentations when a resident, and more recently, national awards for work on prevention of opioid addiction following surgery and cost containment in health care. He has appeared in San Diego Magazine’s “Top Doctors” listing for colon and rectal surgery the last seven consecutive years and was ranked in the top 1% of colon and rectal surgeons nationally by US and World News Reports in 2011. Dr. Worsey serves on the board of the Scripps Accountable Care Organization and on the executive committee of the Scripps MD Anderson program.
He now has more than 20 years’ experience in all aspects of colon and rectal surgery, with particular expertise in minimally invasive surgery for colorectal cancer, diverticulitis, and inflammatory bowel disease. Colleagues have sought his care for their family, friends, and themselves and he receives many referrals for complex conditions and second opinions. Practicing at only one hospital allows close and meticulous care of post-operative patients who are often surprised to be seen both first thing in the morning and last thing in the afternoon, which is his general rounding schedule.
Dr. Worsey’s philosophy is to provide the most up-to-date standard of care using the latest technology while practicing at the top-ranked hospital in San Diego. At the same time, he understands the fears and anxieties that accompany any illness or operation, no matter how complicated, minor or routine. He often tells patients that he understands that their perspective may well be that “a small operation is an operation on someone else.”
On a personal note, Dr. Worsey met his wife Hallie, a native of Illinois, while in Iowa and they have three grown children. His oldest daughter is a professional musician who plays the French horn and his younger son also a musician who plays jazz trumpet. His older son is an artist trained in animation. He participated in a variety of sports, playing rugby for 25 years and captaining his medical school rugby team. Cricket, rowing, squash, and darts were other pursuits and pastimes. Trips to the Sierras and other National Parks take up vacation time and the long-term dream for retirement is an RV to tour the US and Canada.
