Not all surgeons are board certified. Board certification by the ABS is a voluntary process that demonstrates a surgeon’s commitment to professionalism, lifelong learning, and quality patient care. Surgeons certified by the ABS have completed at least five years of residency training following medical school, met all ABS training requirements, and successfully completed a rigorous ABS examination process.

Board certification by the ABS recognizes individuals who have met ABS standards specifically in the area of general surgery and its related specialties. Board certification is different from possessing a medical license, which is the minimum required by law to practice medicine and is not specialty specific.


The letters FACS (Fellow, American College of Surgeons) after a surgeon’s name mean that the surgeon’s education and training, professional qualifications, surgical competence, and ethical conduct have passed a rigorous evaluation, and have been found to be consistent with the high standards established and demanded by the College.
