I am sorry to hear that you did not have a good experience with the MBS program. I also completed the MBS program at Roseman and had a completely different experience than this individual.
I had fantastic mentorship throughout the program (and I also attended in person). Both dental students and faculty were extremely supportive of me! Every faculty member that I talked to was supportive and excited about the MBS program.
During the MBS program, we pick a faculty member as a mentor (typically a faculty member at the dental school). I chose one of the dental faculty members which was highly beneficial. She really cared/cares about me and wanted the best for me throughout the MBS program and currently in dental school.
What did the MBS program promise you that they didn't deliver on? Did you meet the requirements for the guaranteed interview?
I also disagree with the "all they care about is $$$.” I don't believe that is true. Otherwise, they could be charging substantially more for the MBS program. Other programs like Tufts cost $56k compared to Roseman's $27.5k (their dental school also costs more than Roseman's). Also, if you do well in the program, you really should get accepted into the 3-year dental program (everyone in my MBS class that applied was accepted into Roseman's dental school). I have heard that most people have been accepted into Roseman's dental school in the current MBS class that applied and met the pre-reqs.
Also, while you are in the MBS program, a large amount of the courses are taught by pharmacy, future medical, and dental faculty members. So you do have plenty of time to bond with dental faculty that are on the admissions committee. You can go to the 5th floor where the dental faculty are whenever you like. The faculty would always welcome me into their offices when I was on the 5th floor, excited to talk to me. I never felt unwelcome. You can join research projects with dental faculty and form stronger bonds with them. Additionally, some students in my class joined extracurricular dental clubs lead by dental faculty.
It is like anything in life. You get out of the program what you put into it.
The only reason's why I wouldn't see someone getting accepted would be:
1) You didn't preform well in the program (kept reassessing or remediating courses)
2) You didn't meet the requirements (gpa and/or DAT)
3) Professionalism while attending the MBS program
I also agree with what
@StrawHatDMD said. The program is in the early stages and will get more and more competitive especially with the 3-year program.
