I believe their lengthening is surgical, but they can perform non-surgical Girth enhancement. Dr. Carney does most of their male aesthetics over at Morgenstern Rejuvall, and is an exceptional (and well reviewed) Urologist. He also specializes in Reconstructive Surgery and Peyronie's.
I'd do some reading around here, I believe you'll find them to be a great option for getting work done.
Lengthening surgery has been around for a long time. It mostly helps with Flaccid length. A surgical procedure to add significant Erect length has yet to be developed. Save your money and get Girth fillers.
