I've been researching schools a bit and I have found Rush University in Chicago, majority online with few sight visits and VERY well known school, University of South Alabama - online program with a great reputation, and there's UTH- which I have not heard about from anyone with personal experience. An Intensivist I used to work with advised me to make sure that my clinicals were going to be a big variety and ad good quality because you would learn the most and gain the most skill in those rotations.
