It may not be necessary to enroll in a formal post bac. You can do an informal post bac by enrolling and taking undergrad courses at a college/university.
this is an awesome dental pb program! They will help your every step of the way. I highly recommend you to look into it and you can call Dr. Rothman and he will pretty answer all of your questions or he'll direct you specifically to the dental PB coordinator. Best of luck!
