Welcome to OC Surgeons-Saddleback Valley Surgery Division -

proudly serving South Orange County since 1971

We are general surgeons, board certified by the American Board of Surgery and Fellows of the American College of Surgeons.  We treat surgical disease of the breast, gallbladder, colon-rectum-anus, hernias, thyroid, parathyroid, adrenal, stomach, liver, pancreas, spleen, and skin. 

Please peruse our menu to learn about our history, our surgeons and their areas of special interest.  New patients, we encourage you to download the patient questionnaire and bring the completed form to your first visit with us.  Of course, feel free to contact us by phone for any concerns.  We look forward to treating your particular need.

Federal Drug Enforcement regulations require that pain medications can only be obtained with hand written, hard copy prescriptions.  These guidelines prohibit phoned in or faxed in prescriptions.   Any narcotic prescription and/or refill will be e-prescribed during office hours Monday through Friday from 8:30am to 5:00pm.  Please call the office during those times to discuss your needs regarding these medications.


For all our General Surgery patients, please be advised to contact the office for any respiratory symptoms or fever prior to any scheduled appointment to see the physician or if you have a surgery intervention planned.  Mission Hospital has advised us that elective cases at the hospital facility itself should be postponed at this time.  Our physicians will be able to continue to provide services at the office and/or surgery at the Surgery Centers. 

We are continually monitoring the current trends at both the hospital and at the community levels with regards to the international viral outbreak.  Postponement of non-urgent surgery procedures are designed to maximize patient safety.  If you have a visit or procedure scheduled, please call our office for any questions about your concerns in this uncertain time.  Thank you for your understanding.
