Dr. Lazaris performed a four hour long root canal procedure on me. He was extremely careful, patient and precise, taking time to carefully explain each step along the way. A few days later he fitted a new crown. The fit was absolutely perfect. It is clear to me that he a perfectionist and takes much pride in his work. I would strongly recommend this dentist to anyone looking for a best-in-class dentist in Plano, and in fact have aleady sent some of my friends there.
