Dodd Roberts | Director
BSB 287 | 325-674-3710 | 

After a long career in corporate America, Dodd answered a 30 year long call to join God’s work in missions.  He is a 1986 graduate of ACU’s College of Business Administration.  Over his career he worked in public accounting and spent 14 years in Finance at Southwest Airlines.  After leaving the airline Dodd spent several years working in the credit card business where he helped found a large merchant trade organization, and a merchant mobile payments company.  

Dodd has always had a heart for missions and God led him back to the Halbert Center at ACU in 2015.  His wife of 30 years, Kelly, is a teacher in Abilene ISD, and his three children, Travis, Kelsey and Luke, have all attended ACU.  Although the lack of mountains and oceans in Abilene make it difficult, Dodd loves to scuba dive and climb mountains when possible.

Larry came to ACU from Bangkok, Thailand where he lived for 35 years. He spent 10 years growing up in Thailand before enrolling as a student at ACU, but returned to work there with his wife after graduation. Both of their children were born and raised in Bangkok, coming to ACU after high school. Larry’s work was centered in leadership training, but he also was involved in church planting and stabilization. His wife Pam, taught at the International School Bangkok.

When Larry isn’t spending time mentoring students in his office, he’s often preaching at churches in West Texas, traveling to visit family, or skydiving!
