Hi there. We moved from Boston to RI in June and moved our daughter from an allergist at Children's Hospital (who we really liked) to Dr. Berlow in Mystic CT. I seem to like him so far and the staff/nurses there are great. We were going to take her to Dr. Kline in Providence (Robert Kline, Hoppin Street Providence) but I have baby due any day now and when I tried to book with him a few months ago the wait was several months and conflicted with my due date. Dr. Berlow's office was able to take her immediately.
Anyway, Kline in Providence came highly recommended and I would have taken her there =- namely because he is part of a bigger hospital, but the wait and the fact that Berlow is closer just makes things easier. (we are in Westerly). Good luck!
