I had actually heard worse things about the advising at UPenn, but maybe that was during the time when the director was jumping ship for the new Temple program (not sure where that thread is).
I started my post-bac right as this happen (the incumbent director was the one that interviewed me and let me know that I was accepted, then left 2 weeks later). It really freaked me out at first (had that happen at my UG, and it was UGLY), but the office really seemed to pick up the slack. The lady they hired to replace Grace Hershmann (the old director) came really well recommended from UMDNJ-RWJ, and she wrote me a glowing committee letter.
That being said, there are several things I should point out:
1) I never really took advantage of the advising. I spoke with students that were ahead of me and devised my own schedule that way.
2) Just like any school, some of the advisors absolutely sucked. Know it, accept it, read #1 above, and move on.
3) Dr. Ukachukwu (the replacement from RWJ) left last May/June. Not sure what that says about the stability of the program, but students haven't complained too much (at least, not that I've heard around here).
4) The education and professors (again, just from my experience) are all top-notch. I couldn't have asked for better profs. Organization and class structure was great, and most of the courses were modeled to pretty much parallel to the medical school courses (with one prof boasting that she had an 85% pass rate from past students that took exams to test out of histology in med/vet school).
Bottom line is - just work your @$$ off no matter where you go. Doesn't matter if you get into Penn/Temple/Drexel and you tank your courses. Just get A's and move along.
