Ramiro Cavazos at NE Baptist (San Antonio) opinions???

I had a consult with Dr. Duperier but he is on the other side of town.  I'm thinking of switching to Cavazos but he requires a 300 fee for the consult.  It comes out of the total price but I would hate to pay the 300 and not use him!  So before I do that, can anyone tell me what they've experienced or heard.  It's very hard to decide who to use.  Going tomorow so hope someone answers me!
