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!
