This is where I go.
they don't specialize in pregnancy massage but all the masseurs are trained for pregnancy massage (i.e. no massaging the lower back in first trimester, etc). they have a fantastic pregnancy pillow you get to lay and it is so nice to lay on my stomach for that 1 hr!
the lady i go to is excellent and does a great job on the upper back/neck area. I sleep so much better after getting a massage. Her name is Michele Haeberli.
I have been going since about 3 months (I am now 25 weeks).
