April - Dental Assistant

I am very passionate about providing patients with quality and gentle care. My favorite part of dentistry is building a relationship with patients so they trust and feel comfortable in a place many experience anxiety. I have worked in the dental field for the last ten years. It warms my heart to help restore someone’s confidence in their smile and take their life back. Away from the office I enjoy spending time with my son, working out, serving the community and going to church.


Liz- Office Manager

My name is Liz and I am the office manager at Definitive Dental. My goal is to make sure every single one of our patients is given the best quality of care while trusting us with their dental needs. I am also a registered dental assistant. I have been with Dr. Guirguis for about a year and half. I really enjoy what I do, as this will be my 9th year in the field. I’m a Grand Prairie native, Go Gophers! I enjoy spending time with my loved ones when not in the office. I am happily married and a mother to 3 wonderful children who have the same passion for traveling, movies, music, sports, and baking. We also enjoy exploring the world together. Come in and meet our team, I promise you will love us!
