Board Member

Todd has been practicing as a colon and rectal surgeon in Arlington since 2004. He shares the office with his wife Angela, who is a dermatologist. They have two boys; Drew is in 5th grade, and Luke is in 3rd.

Todd graduated from Rice University where he was very involved in the ministry of Campus Crusade for Christ. When he was a child, he went on several missions trips, led by his late father, where they provided eye clinics in Haiti and Ecuador. Thus, it was natural for him to spend one year teaching morals and ethics in Russia before attending medical school in Galveston. He has continued to be involved in international outreach and has visited more than 50 countries. He is currently involved in several innovative Wycliffe translation projects in India where he volunteers with The Seed Company. Now continuing the legacy of missions with his own children, he and his family have been involved in international missions since 2007. Closer to home, they attend Pantego Bible Church where he has served as an elder. He is also an adult Sunday school teacher, and he and Angela host a weekly home group. He enjoys being the Cubmaster of Cub Scout Pack 323.

“I count it an honor and privilege to help lead this school that is helping to lead our children toward Christ-like character. Education has opened many doors for me, and I am committed to seeing our students enjoy those opportunities as well.”
