And what is important to you? Prestige? Money? Location?
Hopkins has the name, and while I think Kaiser will build a great name for itself, it doesn't have it yet. I'm committed to Kaiser and my concerns over other choices were mostly prestige and what connections I would have at those institutions. Money, lifestyle, location were all in favor of Kaiser. Prestige, low academic risk, and networking benefits were not in favor of Kaiser compared to a place like Hopkins.
If you want to go into academia or neurosurgery, Hopkins can open big doors in both those areas because of resources and connections. Kaiser, on the other hand has immense, and very impressive, resources to throw at its students, just maybe not comparable to Hopkins Neuro.
If you're in the groupme, I recommend asking some specific questions of the already committed students and see their train of thought. Speaking with Dean Schuster is also really fantastic, I'm sure he'll happily make time for you.
