Depends on insurance and where you'll be. Are you willing to pay out of pocket? If you have United Behavioral Health (UBH), then you'll probably have an okay time finding someone. A lot of the good ones at least accept UBH in my experience.

You really can't go wrong with someone from or affiliated with MGH. Only problem is that if you don't actually physically live in the city, then getting down to Charles St and finding a parking (35 Fruit St parking lot) is a pain in the *** (not to mention expensive as hell).

It really makes a difference if you're living downtown or not, because traffic is godawful. I personally would not visit an excellent psychiatrist if it meant I had to drive 1 hour in dead stop traffic each way. Massachusetts always seems to win "worst drivers of the year" award, tied with NJ. There's a reason they're referred to as "Massholes"...
