In the Spanish ones, he is highly recommended, together with Dr Juan Couto, Dr José Lorenzo, and Dr Rafael De Freitas, but he is more affordable (maybe because his clinic is in Portugal) and his overall results are simply amazing, and he is the only one who performs the whole surgery (drawing, shaving, anesthesia, extracting, and grafting).
I love the work of those 4 doctors, and they are all considered among the best surgeons in the world.
