I've got a complete mess of a scar that I need to get fixed

[john74]

Hi all,
I had 2 hair transplant surgeries done a number of years ago that left some pretty nasty scars on the back of my head. I've already had one scar revision surgery done about a year ago to cut out part of the scar, but to be honest I think it actually may have made the scar slightly worse (wider). I'm looking for a doctor that's skilled in scar repair and is preferably on the east coast of the US. Any help would be appreciated. I've attached a pic for reference.
