The best that I know of is Dr. Richard Domino, a French doctor, who works out of Clinica Abreu in Santo Domingo. He did a knee and hip replacement on my wife and is excellent. His partner, Dr. Faris Werr, is German. I suggest you email Dr. Domino at
orto_medi@hotmail.com with copy to
drfarisfwerr@hotmail.com
You can tell them that Ken De Pree recommended that you contact them.
