In terms of doing all the tests your PCP recommends in as few visits as possible, St Vincent's is better. In terms of receiving a referral when your insurance requires one, UMass. I think that's probably because they're a larger network, though. I believe both options have primary care offices on their local campuses. Again, this is from local people who are dealing with a number of health concerns such as chronic cellulitis, osteoarthritis, and vision issues, and UMass was better for them.
