I highly recommend RMA of NJ (I was a patient of RMA of New York but can't in all honesty recommend them anymore). I had IVF and their successes are second only to CCRM. I hope you don't have to go the IVF route but I swear by RMA NJ.
I go to RMA of CT. I don't have experience with RMA of NY or NJ but if they are anything like CT, I would recommend them. RMA of CT is a wonderful group!
