The Physicians

Mathew Isho, M.D.

Jeffrey Toman, M.D.

Our office is comprised of two surgeons, Dr. Mathew Isho and Dr. Jeffrey Toman, who are committed to providing excellent care for patients with colon, rectal, anal, or other general surgical problems. By working at three office locations, doing procedures at a number of outpatient surgery centers and endoscopy centers, and providing care at four hospitals in San Diego, we strive to provide care that is flexible in meeting the needs of our patients.


A colon and rectal surgeon is a physician who has specialized in the treatment of conditions related to the colon, rectum, anus, and small intestine. This type of surgeon has completed full training in general surgery and has completed additional training specifically in the field of colon and rectal surgery. Both Dr. Isho and Dr. Toman are dually board certified in colon and rectal surgery and general surgery.


Following the completion of a training program in General Surgery, board certification is offered through testing by the American Board of Surgery. The purpose of this certification process is to establish that the physician has sufficient breadth of knowledge and practices in a safe manner. Similarly, following the completion of a fellowship in Colon and Rectal Surgery, testing is offered by the American Board of Colon and Rectal Surgery. This board certification cannot be attempted until board certification is attained in General Surgery. Both Dr. Isho and Dr. Toman are board certified in both colon and rectal surgery and general surgery.


As surgeons, we evaluate and treat patients in our office, perform outpatient procedures and operations, and perform operations on patients who require admission after surgery. Office treatments may be provided for a number of conditions depending upon the severity of the problem. Such conditions include ofice treatment of bleeding and prolapsing hemorrhoids, fissures, pilonidal cysts, and warts, among other conditions. Outpatient surgery is also possible for a number of conditions, depending upon the severity. Conditions that we treat as outpatients include hemorrhoids, fissures, abscesses, fistulas, warts, some rectal cancers and polyps, and pilonidal cysts. In addition, a number of “general surgery” conditions may be treated by us as outpatients, including hernia and gallbladder surgery. In addition, number of conditions can be treated only with larger surgeries, which typically require admission to the hospital to provide adequate care. As colon and rectal surgeons, we approach every patient’s problem with a comprehensive approach. By having the training and knowledge necessary to provide specialty care, we understand the small differences that permit treatment to be tailored to each person’s needs.
