We are often asked “What does the A.P.C. after Dr. Mastrovich’s name mean? Is it a designation for his restorative dental expertise?” It would be a lot more exciting to be able to say that it indicates the high level of confidence patients and colleagues have in him! Or for it to mean “Always Painless and Caring”. Both of which are true. But the reality is simply that it means “A Professional Corporation” and once a dentist incorporates the choice is between APC and PC, and it must be on anything representing the business (signage, stationary, websites, etc).
