If I worked at DHMC, I’d be happy living in any of the places you mentioned. As others have mentioned, housing supply is tight so I would suggest keeping all of them in consideration vs. choosing a specific town now.

Hanover is on the pricier side due to proximity to the college. Driving around there on game weekends, graduation, etc. can be a pain, but the downtown area is nice.

WRJ would be my pick for restaurants and bars. Wolf tree is a fantastic cocktail bar and both Trail Break (tacos) and Big Fatty’s BBQ have solid food and beer lists. That being said, you obviously don’t have to live in WRJ to enjoy those places. Leb, Hanover, and Norwich are all pretty quick drives
