Welcome to San Diego Colon & Rectal

Located in La Jolla, California, San Diego Colon and Rectal Surgeons is a practice composed of two experienced, fellowship-trained, and board-certified surgeons who are dedicated to the practice of high-quality, state-of-the-art colon and rectal surgery.

The team, led by M. Jonathan Worsey, MD, and Keith A. Beiermeister, MD, is committed to providing compassionate, individualized care to their patients utilizing the most modern diagnostic and therapeutic techniques available.

The practice specializes in all aspects of colon and rectal surgery but has particular expertise and experience in minimally invasive colon and rectal surgery, colon and rectal cancer, inflammatory bowel surgery, and complex re-operative surgery.

The vast majority of major operations are performed with both surgeons present to ensure an efficient, safe, and successful procedure; this is quite unusual in most surgical practices today. They do not employ allied health providers, and direct and specialized care is given by the surgeons at all times. The team prides itself on excellent surgical outcomes and the provision of the best possible care and attention.

I had my J-Pouch scoped after 10 years (I know… not good) and Dr. Worsey did a fantastic job! His nurse who assisted and the lady at the front was also very nice. I also got to see the procedure on the TV screen as it was being done. So cool!!

Dr. Worsey is an excellent Doctor in his field with an appropriately excellent staff. I know that I am in very competent hands when dealing with Dr. Worsey. We, his patients, are very lucky.

Thomas R.

Dr Worsey and Beiermeister have taken wonderful care of me over the past 3 years. From consultation to management of complications from surgeries elsewhere, and finally closure of my Ostomy. Both Doctors and their staff are helpful, courteous and professional. Complications from 5 prior surgeries left me quite anxious. Yet, both Doctors took the time to listen, explain and reassure me every visit or hospital stay. Both Doctors are empathetic and do not rush you despite how busy they are. I strongly recommend Doctors Worsey and Beiermeister and their staff, and would encourage anyone to see them for related matters.
