Valeri Alarcon

Office Manager

Hola, my name is Valerie Alarcon. I am proud and excited to say I'm the Lead Assistant at Longhorn Pediatric Dentistry and Orthodontics. I've been with this office since 2004 (with the exception of two years). When I'm away from the practice, I love spending time with my husband, Alvaro, and precious son, Wyatt. Either having a movie and popcorn night or grabbing a colorama coloring book to help restore my soul. I love good company on the weekends with a backyard BBQ or Sunday Funday Dinner. Fun fact, I gave birth to a one pound five ounce miracle baby boy.
