Dr. Doan is accredited with the American Academy of Cosmetic Dentistry, which means that he has passed examinations demonstrating the highest level of skill and artistry in aesthetic dentistry. He is known for his conservative approach to smile makeovers, often using a no-preparation technique for porcelain veneers. He is also known for his meticulous attention to detail with his smile designs. He will create the smile on consultation with the patient with a digital smile makeover that he does himself, and will fine tune that design with a provisional smile makeover. Only when the patient is perfectly happy with the provisional makeover will he have his master ceramist make it in porcelain. Other San Diego dentists have voted him a top dentist in the San Diego Magazine survey. He also provides nitrous oxide and oral sedation for anxious patients.
