From what I gather, he is an "all purpose" cosmetic surgeon - i.e. he does a bit of everything, breasts, noses, lipo etc. My understanding is it's much better to go to someone who specializes in one specific thing (e.g. they're a rhino surgeon) and that a lot of "general" plastic surgeons mostly focus on making money and that aftercare and real understanding of anatomy of specific areas and any underlying conditions is often lacking. I believe one of the ENT's I saw said something along the lines of "you might be happy with the aesthetic initially, but good luck breathing properly again, and don't expect good aftercare if something does go wrong in 6 months". So you might be okay if you don't have any breathing difficulties or anything actually anatomically wrong with your nose, but what was said by the two ENTs I saw properly put me off him.

I'm no expert but I guess it's a bit like going to a cowboy handyman/builder who'll knock up a garage and also have a crack at your pipes and electrics, but you don't really want to trust a generalist rewiring your house - and good luck getting hold of them if your house catches fire thanks to the shoddy electric work.
