any one use dr sprunger in az
Never heard of him in over 8 years here and on other DS related sites. Did a Google search and could not find him, at least not in AZ (you didn't say where your sister is). I very much doubt this is a DS surgeon. Are you sure you have the name right? There is another surgeon in AZ that comes to mind with a somewhat but not really similar name, and he's someone I wouldn't recommend.
