In my opinion Dr. Ferrero is an excellent surgeon. He performed a thoracotomy and Heller myotomy on me to relieve constriction in my esophagus. The surgical scar is barely visible. I was in hospital for three weeks. On visits he was friendly and approachable, very kind as well as thorough in making sure that my lungs were drained and functioning well before allowing me to go home. On follow-up visits to his office he continued to be friendly and approachable and concerned about my welfare. I highly recommend him as a great surgeon and wonderful human being.
