After receiving horrible dental treatment for my 2 children at another dentist, Dr. G was highly recommended to me by a friend. He is very knowledgable and wonderful with my children! He answers all my questions and explains everything to me in depth. My kids LOVE going to his office and it is no longer a fight to go to the dentist. His front office staff at the Centennial location are friendly and wonderful. They give excellent customer service and are always helpful with insurance questions. I recommend Dr. G and his staff to everyone I know! Their waiting room is very children friendly with a TV showing kids shows and two video game TVs with controls so everyone can play. I can't say enough good things about the Centennial office!
