For someone who is very nervous in a dental chair, or even visiting the dentist, my experience with Dr. Williamson and his staff has been more than pleasant. Not only are the concerned for your comfort, they truly ask all of the right questions to keep you comfortable and less "white knuckled." They go over thoroughly their dental plan, keeping you informed of all procedures and associated costs. Finally found my forever dentist!

I’ve been told that I have dental PTSD, I do have pretty high dental anxiety. I needed dental surgery and Dr Williamson worked out a plan with me. On the day of surgery we agreed to IV sedation. They started with gas to help me relax so that I didn’t even feel the IV insertion. Afterwards I had no memory of the procedure, exactly what I wanted. Everyone in the office is like my best friend. They are an awesome team. Recommend them to everyone.
