I didn't really get involved, but we have a lot of clubs available to students, from interest groups to cultural groups to business groups. You can also start virtually any group you want. We even have a brewer's guild for beer lovers.
Least favorite part is probably lack of proper residency application counseling by the administration. You'll need to search out mentors in your field, which is very easy here at Loyola, because the administration is not super helpful when it comes to specific things, and has on several occasions given erroneous advice ("don't apply to this field, you won't match, etc.) that is unwarranted and there have been a handful of issues. Our students don't have any issues matching and we do incredibly well, but we generally ignore our admins (who are well-intentioned, however).
Also, Loyola's strengths are 1) clinical competence; 2) social competence. Clinically one of the strongest sides, and we know how to deal with patients emotionally and socially. However, academics, at least during my M1/M2 year, aren't as organized, and you need to be a self-starter/ independent learner or at least get ready to develop those skills more at Loyola, because we are not the best organized didactic program during M1/M2 years. Certainly doable, but Loyola expects a lot of its students, namely, being proactive self-starters.
