Dr. Smith is skilled in all aspects of general dental treatment and continues to keep up to date on the latest treatment techniques and technologies. He participates in continuing education courses of all kinds, including implant dentistry, in which he’s especially interested. Dr. Smith considers Pecan Tree Dental his home away from home, and his patients and staff are his extended family. He strives to put each patient at ease with his sincere, friendly chair-side manner and honest treatment approach.

Dr. Smith is married and has two sons, whom he credits with having inspired his gentle and patient manner when treating young patients, and for his dedication to providing free dental care to all mothers on Mother’s Day. In his spare time, Dr. Smith volunteers with his church and as a Youth Boy Scout Leader, having been a Boy Scout himself. He also enjoys hiking, working out, and dining at local restaurants with his family.
