I've had two procedures with him and cannot be happier, the results I had are as good as any hair transplant I've seen anywhere.
In my opinion and experience he's right up there with the very best in the world, though if you want a mega-session then Hasson & Wong will do more grafts in a single session.
It's debatable that some of the well known American surgeons may well be at least as good if not better and there are certainly some excellent results to be seen around the forums from them; but for my money you won't go wrong with Dr. Rogers.
All that said, it won't hurt you to have consultations from other clinics around the world too, or at least make contact with them. That way you can be sure that you go into the procedure with all the facts and options clear in your mind.
