Jill – Office Manager

Hey, my name is Jill. I’ve spent many years in dentistry. The best part of my day is when a patient leaves our office grinning from ear to ear because they love their smile transformation. I live in McKinney and have lived there for most of my life. I’m a mom of 2 adult children, a “glamma” to 2 grandbabies, and a mom to 1 super spoiled pup! I love professional football and you can find me in front of a big screen anytime there is a game. Most importantly, I might have a mild addiction to diet Dr Pepper and sonic ice. 

Courtney – Treatment Coordinator/Dental Assistant

My name is Courtney. I have been in the dental field since 2018. I got married to my best friend & love of my life in March of 2024. I have 2 fur children Bella and Paisley. I also have a stepson that keeps me on my toes. I have a niece, who I spoil a lot. I love to be outdoors and go on new adventures with my husband. We also love trying new places to eat. When we’re not at home relaxing, we like going to visit family and friends. 

Berkeley – Registered Dental Hygienist

My name is Berkley and I am a Plano native with West Texas roots. I graduated from Texas Tech with my Bachelor of Science in Kinesiology in 2015 and continued my education at Amarillo college and graduated with an associate of science in dental hygiene in 2020 where I was class president.

I am passionate about making patients feel like family and providing exceptional care regarding all oral hygiene needs. I love spending time hiking, skiing, or water sports on the lake. I love football and will always be rooting for my Red Raiders or Dallas Cowboys. As a former college softball player i still like to get out on the field and play slow pitch, and attending tournaments when possible. I have a 2-year-old rescue dog named Remi, who goes with me anywhere she can. I love spending time with friends and family and I will never turn down a group game night.

Jessica – Registered Dental Assistant

I have been a dental assistant for over 2 fun filled years. I grew up in Lake Dallas and just recently moved back to the area to raise my two little girls. When I'm not working, we like to explore new parks and creeks and we have the best movie nights. 

Brianna – Registered Dental Assistant

It feels as though I've been in the dental world from the time I was young, from my many dental humanitarian trips with my Dad.  However, over the last few years I realized my passion for dental assisting and decided not to look back. My husband and I moved to Texas in 2023 to be closer to family and further our professions. Together we love trying new sushi places, visiting national parks, and anything that keeps us laughing!

Eryn – Hygiene Coordinator | Registered Dental Assistant

Growing up, my dad has always said if he didn’t choose counseling, he would have worked in the dental field - and I understand why!

Working in this field has been such a blessing for me and my family, and has allowed me to help people take better care of themselves and their smiles. Here at Prairie Creek Dental, it is such a joy to meet so many people to help and encourage and take care of here in Lewisville.

When I’m not in the office, I love trying new recipes, reading, swimming and spending time with my husband.
