I just had my surgery through Dr Stevenson Nov 15th. Very nice guy.. i also did research but didnt find alot either. He is actually a stomach surgeon so he not only does bariatric but all kinds of stuff. he has a nice office in chandler you will meet him at. from what i understand he still works in tuscon. like he has two offices. umm my surgery went well i had no complications. it was outpatient.. i am down alomost 50 lbs so far since november. i talked to this old couple in his office on my pre op visit who were there for some surgery stuff non weightloss related and he said dr stevenson operated on him and his wife and he really liked him as well. so i dunno. cost wise is if your insurance wont cover much evolve seemed to be best price with bcbs.. i did quotes with wliaz and true results. evolve gave me best quote. my insurance sucked he has had no fatal issues i asked him. and he is super strict on diet. word of advice he will want u to go on shakes. i used slim fast ADVANCED nutrition. make sure advanced the other slim fast have to much sugar. but after u go to his office u will be more comfortable. i thought it was odd to talk to people in tx from evolve though like it was a scam but there not its real. the surgeons at true results and wliaz and mainly at any of these weightloss places are contract surgeons. not really inhouse ones. maybe evolve gave him a better cut or deal? idk
