Department of Further Amplification: Comment on Advisors:
Advisors are familiar with what is required for admission to all health professions schools. They don't necessarily advise on the careers, but on how to meet admission requirements, etc. The interface is college
rofessional school admission. It is not necessary for an advisor to be a physician, dentist, veterinarian, PA, etc. Their speciality is advising undergraduates on matters related to college curriculum, MCAT/DAT/VCAT and other such exams, the mechanics of application, and to help students deal with problems arising in courses, etc. As in any profession, some advisors are more proactive than others, more available than others, more user-friendly than others, more helpful than others. Advisors often have informational resources available that students don't have or don't even know about.
Some few advisors are fact MDs themselves, many are full-time tenured faculty, commonly in biology and chemistry departments but sometimes outside the sciences, others operate out of college counselling offices. At some universities there are different advisors for different colleges on the same campus (such as General Studies, the liberal arts college, the agriculture school, the engineering school).
Many medical schools and dental schools want or look for letters originating in the advisor's office, because they are familiar with the writers, know what the letters mean and which they can trust.
At least, almost all colleges have someone--even if it is in the general academic advising office--preprofessional students can turn to. Seek, and maybe ye shall find.
There are advisors in the professional schools for the interface between the professional school curriculum and whatever comes after. That is their speciality.
