Grecia Mora Bernal
Oral Health Educator


Grecia Mora Bernal is a Registered Dental Assistant working at PDI Surgery Center. Her mission as PDI’s Oral Health Educator is to improve our patients' dental and general health by providing them with education on oral hygiene and nutrition. One of her main goals is to provide our families with the necessary support and motivation they need to prevent tooth decay and make good nutritional choices. She loves when she hears a parent say, “Wow, nobody ever told me that! If I would have known, my child would not have all these cavities!” Grecia says, "It is truly motivating to see patients leave PDI cavity free and, most importantly, pain free."
