As a general dentist, I enjoy seeing patients of all ages, especially children.  The staff and I are working hard to make sure that children feel comfortable at Coweta Dentistry.  During the time I spent working in the pediatric department at UAB, I learned the latest techniques to ensure that children have a positive experience in the dental office.  I plan on using the latest technology and my experiences there to make both children and adults feel welcome and at ease at Coweta Dentistry.
