Birthing center?

Trouper
Hi ladies. This is will be my 3rd baby after 2 previous c-sections 5 and 6 years ago. I'm very prepared for the possibility of my beloved OBGYN of 7 years NOT letting me attempt the natural birth (vbac) I so desperately want. I've been looking into birthing centers but would love to hear recommendations or experiences from women who have delivered at a birthing center in Phoenix AZ. Thank you in advance!
