He has appeared on television, authored books, and won awards for papers appearing in national peer-reviewed journals. He trains doctors from around the world. Most importantly, he has thirty years of experience in tailoring vision therapy to meet the needs and goals of each patient. It is one thing to provide vision therapy.
