Dr Castillo is a model for all pediatric dentists!

Again, Dr Castillo is a fantastic, caring, nurturing pediatric dentist who goes beyond what should be expected. Because there is a lack of dedicated hygienists/dentists, she stepped up to take adolescent children who should not be seen in the pediatric area. You need more dentists like her!

There was an emergency with his gramma during the visit. The entire staff was amazing! Kept my children calm, got her help and stayed in constant contact with me until I could get there. So professional! Doctor even contacted me later at home to make sure everyone was ok.
