S.L.
I don't know if this will help or not. I had my son at the Birthplace at Wellesley that is now closed. There are now only 2 birth centers left in the state. One is in Cambridge and the other is on the North Shore.
I know that CNM's are used less in Central and Western Mass than they are around Boston.
I do believe that there are midwives that have privileges at Landmark in Woonsocket.
I can tell you that my Birth Center birth was absolutely amazing even though it wasn't "birth plan" perfect. It was a 2 1/2 minute ride to the hospital so I never felt if I or my son needed emergency care it was too far away.
