Before even calculating mileage, I thought that the two Poughkeepsie hospitals (St. Francis and Vassar Brothers) were the closest, but Sharon Hospital in Sharon, CT is just about is close, if not a little closer depending on where in the town you live. The difference is that two are to the west and one is to the east, but while I've never been to Sharon Hospital, I know that the quality of care in the Poughkeepsie hospitals is quite good. I'd say 20-30 minutes for any of them.
Northern Dutchess Hospital in Rhinebeck isn't that close; let's say about 40-45 minutes.
