What is a Board Certified Pediatric Dentist?

Not all pediatric dentists are alike! It is important to seek a pediatric dentist that is board certified by the American Board of Pediatric Dentistry.

A board certified pediatric dentist, or Diplomat, is a pediatric dentist that demonstrates an exceptional knowledge and expertise at a standard not possessed by other dentists.

The American Board of Pediatric Dentistry verifies credentials and a voluntary examination must be successfully completed. A dental practitioner with this level of certification exhibits a drive and determination for excellence in the field of pediatric dental health.

Dr. Greg and Dr Kelsey have both attained certifications with the American Board of Pediatric Dentistry, which represents the highest possible credentials within the field of Pediatric Dentistry. When your child is in the care of a board certified pediatric dentist, they are being treated by the best of the best!

Meet Doctor Kelsey

Kelsey Stehli grew up locally on a blueberry farm in Mantua, Ohio. She graduated with honors from Ohio State with a degree in International Relations and spent 6 months in Brazil post graduation working in an orphanage. After spending time with the children there she felt driven to develop a skill she could use to help children and discovered her love for dentistry. After a grueling year of science prerequisites, she was accepted to Ohio State University College of Dentistry where she graduated with honors. Following graduation, she went into a two year residency program at Rainbow Babies and Children’s Hospital where she focused her skills on pediatric and hospital dentistry. During residency she served as chief resident and was even asked to stay on as a part time faculty member post graduation! Dr Kelsey recently finished up work for her board certification and is now a Diplomate in the College of Diplomates of the American Board of Pediatric Dentistry.

Kelsey loves treating children and feels very fortunate to be able to participate in the care of children from her own childhood community. She enjoys each child’s unique personality and strives to provide individualized care specific to each child’s needs.

When she is not scrubbing away “sugar bugs,” she enjoys doing yoga, water sports and spending time with her family and friends including her husband Ray, her cat Miko, and her gigantic Bernese Mountain Dog Atlas.
