Katrina Thornton

Patient Coordinator

I am the patient coordinator at Coppell Pediatric Dentistry. I completed my RDA in Corpus Christi Texas and I am a seasoned veteran in pediatric dentistry. I am here to answer any questions regarding your child’s dental care including treatment, insurance, account information, or your appointment needs. Some parents don’t like going to the dentist, but if we can get their child comfortable in our office hopefully, we can help parents get comfortable too. I love working with children of all ages, and their parents. Working in a pediatric office is full of rewards, including the best stories and smiles ever! I have two beautiful daughters Danielle, and Dayna, and one handsome grandson Jason, and I’m married to my wonderful husband Shannon. While I’m not at the office I enjoy family time,traveling, and casino fun!

Hey y’all my name is Ayaah and I’m a registered dental assistant here at Coppell Pediatric Dentistry. I have worked with kids in the past and I loved it, so I knew I had to pursue a career in pediatric. Seeing the comfort and smiles on the children’s faces makes my job so rewarding. My goal is to make sure you and your children go home happy and comfortable with their visit. I’m a class of 2022 graduate, and went straight to dental assisting school.
