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.

My name is Gabrielle Requenez. I was born and raised in Carrollton. I've been in dental for almost 8 years, and I have been with Dr Holbrook for a little over 3 ½ years, I can't see myself anywhere else. I have furthered my knowledge of dental in ways I didn't think I would. I have a beautiful little family that brings me so much joy!

My son Jaxson will be four this year and he keeps us very busy; we enjoy any outside activity we can find and are looking to play baseball soon!

Our favorite place to go is the beach, growing up we would always visit South Padre Island because we have family close by. So, I try and keep the same thing for my family, and we try and hit the beach every summer!

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!
