Meet Our Doctors

All doctors at Smart Pediatric Dentistry are either board certified or board eligible pediatric dental specialists.


This means that after four years of dental school, they attended two or more additional years of specialty training focused primarily on treating the dental needs of children and adolescents. Above and beyond a pediatric dentist can take additional board exams both written and oral to become board certified by the American Board of Pediatric Dentistry. Our main focus as pediatric dentists are to inform and teach parents about their child’s oral health, do the highest quality dentistry possible, do it safely, and do it in a way that is most comfortable for our patients and parents.
