Dr. Sang Lee is a leading colon and rectal surgeon practicing in Los Angeles, California. He specializes in the treatment of colon and rectal cancer, rectal prolapse, benign conditions of the anus and rectum, and inflammatory bowel disease.

After graduating from Johns Hopkins University, Dr. Lee received his medical degree from New York University School of Medicine before going to Beth Israel Deaconess Hospital, Harvard Medical School for his residency training. In the following years, he went to New York Presbyterian and Columbia Medical Center for his fellowship training. Dr. Lee has performed more than 1000 laparoscopic colon and rectal surgeries, and he is the top expert in single incision laparoscopic colon surgeries in the country.

He also has developed a minimally invasive technique to surgically treat Crohn's disease and other benign rectal strictures.
