He spent so much time speaking to me. He asked follow up questions. He listened to my answers without rushing me. He did an actual physical exam. He was knowledgeable and thorough. He picked up on issues that even my primary missed. His staff was kind and helpful. I feel lucky to have been referred to him.

Dr. Lee is the best dentist I’ve ever seen. He is so wonderful, kind and caring. I have had no hope for my issues, but he is working hard to make me feel better. I would highly recommend Roar and Associates, especially Dr. Gannon Lee!!
