Dr. Eppley did my FFS/revision after another well-known doctor really messed me up. Nobody else really knew how to fix me, but he did. He totally redid my "type III" forehead procedure (using bone grafts) and removed some inflamed/infected bone putty as well as shaved down my orbital rims, which the other doctor had neglected to do. The difference was amazing, and to this day (I am 5 years post surgery with him) I am extremely grateful to him for what he was able to do for me. He completely fixed both the functional and cosmetic issues. He has both medical AND dental degrees, so it's not accurate to say he's a "dentist" who got into plastic surgery; he's a plastic surgeon AND a dentist, which makes him ideal for chin/jaw work IMO.
Do not buy the negative stuff about him online. Years ago he did a facelift on a patient who turned out to suffer from serious mental illness. She became delusional and started to believe that her face was deformed, and she ended up trying to staple her own skin back up in a kind of DIY facelift. Anyway, she started stalking him and created hundreds of sock puppets online to try and ruin his reputation. He was forced to take her to court, and won a restraining order/libel case against her. She was ordered to take down all the false claims, but after a "revision" by somebody else (who she also claimed was bad/out to get her/etc) she killed herself. Unfortunately the legacy of her actions lives on with all of the fake "reviews" she posted. Any surgeon can have less-than-happy patients, but in this case it's a matter of public record that he was the victim of a smear campaign by a deranged individual. I did a lot of research on him before I ever let him near me, and he's well-known as an excellent surgeon and does a lot of amazing work on children with serious cranial defects.
So, I can speak from personal experience when I say that, at least for bony facial work, I think he's top notch and would happily recommend him to anybody I cared about. I may yet go back to him for chin/jaw work and a facelift in the future.
