DO Doctor of Osteopathy
PC Professional Corporation (that one's more like the abbreviations "corp" or "inc" -- doesn't have to do with the doctor's training).
The P.C. included in a Doctors name probably came after the name of the facility he works at and the P. C. stands for private corporation, meaning he owns the facility, or part of it.
It could stand for Doctor of Optometry, or Doctor of Osteopath.
