NYC/NJ or Boston/Cambridge recs for darker skin? Coolglide or Lightsheer?

Hi all,

I’m looking for places to start out (never consulted, etc.) with LHR on body (underarms, bikini, legs). I am pretty sure I have Type IV-V skin, and am judging that Coolglide (Nd:Yag long pulse) and Lightsheer(diode) might be the best to try.

Any recs for NYC or Northern NJ? for Boston/Cambridge, MA?
