Christina Watson-Sanchez


Christina is a very passionate person who believes that good things come to those who work for it. She finds great joy in planning life projects. While serving in the military, Christina learned to adapt and overcome in a variety of situations. She is driven by the motivation to help others help themselves.

Christina enlisted in the military after graduating from high school with dreams of seeing the world—not knowing she would also meet her future husband! While in the Marine Corps she had the chance to travel to Japan, Australia, Guam, South Korea, and Iraq. Christina served four years; she was stationed in Japan for two years and deployed to Iraq for 11 months. During that time she learned the importance of fostering good rapport and mediating tough predicaments with her fellow Marines. Upon her honorable discharge, Christina went on to pursue a degree in Sports and Exercise Science.

Upon leaving the military, Christina returned to Florida, earned her degree, and got married. From a small town in Florida (with a population of less than 1,500 people), she moved to Texas and continued to travel, adding Jamaica, Belize, Spain, Morocco, and Haiti to her passport stamp collection. Her goal is to visit every continent. When she isn’t working, she snuggles with her husband Chris, her feisty, two-year-old daughter, and her dog—all of whom she dearly adores.
