Infertility Support Group
In vitro fertilization is one of the most common and utilized ways of treating conception problems. This support group is dedicated to those beginning their journey with IVF and needing support. Join the community and share your experiences, advice, and story with people going through similar challenges starting a family.
So the point of my LONG story (sorry about that) is that maybe once your RE knows you are looking to leave he could work something out with you. Otherwise I would call your insurance company to see what Infertility Doctors are in your network. Then go from there.
Try going to this site and looking up some centers in your area and their stats. Good luck!
