After many years of practicing endodontics, teaching and lecturing all over the world, I am very pleased to finally have an easy way of communicating all that I have learned with the dental community in an easy and interactive way. If you are a patient or a dentist, I will be happy to answer any questions you may have concerning endodontic or implant therapy.
