Expert Team

The Inflammatory Bowel Disease (IBD) Center's expert team of specialists is highly skilled in treating adult and pediatric patients with all forms of inflammatory bowel disease. Physicians at the IBD Center maximize expertise in research to deliver personalized care using the latest treatment options and procedures, including the latest antibody therapies (e.g., Remicade, Humira, and Abatacept).

Many of the physicians who have medical staff privileges to practice medicine at
Cedars-Sinai Medical Center are independent physicians, and not employees or agents of the hospital. These independent physicians bill separately for their services. You should contact your physician to determine their status and billing practices.
