DS REVSION W/Dr.Michael Schwartz Minnesota questions

Dr Buchwaldf from UofM did my revision from VBG to DS, and it was open. Where is Dr Schwartz located? As far as I know, there are 3 DS surgeons in the metro (1-2 that I would say are experienced enough for revisions), and 1 at Mayo, but I don't know his name - and I don't think he's been at it long enough, either, that I would trust for a revision surgeon.
