Thomas,
I can chime in here from experience with Dr Arocha ,you will be in very good hands. Everyone gets nervous of course. Dr.A and his team will take great care of you.
I'm at almost 14 months post op and can tell you for me, everything he said would happen did, (healing time, minimal shockloss in donor area/none in the recipient area. His work is very very clean. 4 months post op the magic began.
Hope this helps,
Scott
