I don't know about in or around Austin, but I do know about San Antonio. My transplant clinic is good - Christus Santa Rosa. Methodist Hospital and University Hospital both have great clinics/teams, as well. Both of those hospitals do more transplant a year than Christus, but Christus is very picky about their live donors, which isn't a bad thing necessarilyl. They have their problems, but overall I was very satisfied with my care pre and post surgery.
I was told the average wait time in San Antonio is about 5 years and I think they said Dallas was 4. I'm not sure about Austin, but I do love Austin. Are you going to college there?
Welcome to Texas! (a little early)
