You would like Rochester, MN, where I grew up. It's home to the world-renowned Mayo Clinic, and there are many presentations on medical themes. Most are for the medical staff, but not all.

Because it's a research hospital, it draws in people from all over the world. The late King Hussein of Jordan used to visit frequently. More interestingly, the Dalai Lama occasionally visits and gives talks. Those are almost always just for clinic staff, though.
