Plastic surgeons in Northern New Jersey
a lot of people in that area go to Dr. Capella. He specializes in body contouring for massive weight loss patients (which is what you want - or at minimum, a general plastic surgeon who does a BOATLOAD of these surgeries, since it's supposedly a complicated subspeciality). Some people in the NYC area also travel to DC to see Dr. Joseph Michaels - who's also a specialist in that area (massive weight loss patients)
