Teonna “T”
Office Manager/Registered Dental Assistant
Teonna began at our practice in November of 2013 and graduated from Concorde Career College with Honors and Dean’s List to obtain her DA certificate. She continued her education to complete state testing and received her RDA license. Teonna has always loved dentistry, ever since she was a little girl. She remembers being excited to go for her check up and see what the latest materials and gadgets were. She would even ask to assist if a family member was having treatment completed.

She immensely enjoys working with her team as they have become some of her dearest friends–so much so, she considers them family. Teonna’s communication and leadership skills bring so much to our team. Plus, she brings cupcakes and donuts–who wouldn’t be happy with that? She values her team and in return, they value their patients.

Teonna and her husband have three boys: a 13-year-old, 6-month-old twins, amd two girls ages three and four. Teonna stays busy with her new baby boys and loves being that one mom cheering in the bleachers.
