How can I check the credentials of a pediatric dentist if they aren’t listed with ADA?

I want to take my kids to their first visit, but want to make sure we go to a reputable dentist. I buy drugs online no prescription check with ADA and I could only find that one dentist on my insurance list was active. That's out of ten listed. But nothing showed letting me know if they had complaints or suits against them. What should I do?
