Because I have never been to Dr. Vaughan, I cannot give much of a review. Dr. Armstrong is my doctor, but the changes seem as friendly and helpful as before. I assume Dr. Vaughan provides the type of service, I would recommend his practice to any of my friends who need a dentist. All the staff and hygienists are so kind and I treasure their friendship as well as their expertise. I've been with Dr. Armstrong for around 18 or 20 years and he's always been the best!!
