Hi Justin,
If you mean admissions personnel (i.e., directors of admissions, etc) contact information, the Sept 5th issue of JAMA is dedicated to medical education. In one of the appendicies in the back, there is a list of all the medical schools and the deans for each school. Otherwise, you can use the MSAR. If you mean counsellors at each school that advise pre-med students, I am not sure about that. Hope this is helpful!
