Background

I enjoyed a 30-year career in industry, most of that at the Pacific Northwest National Laboratory in Richland WA.  I was involved in research, development, and deployment to solve problems in hazardous and nuclear waste remediation for the U.S. Department of Energy and in radiation detection for the U.S. Department of Homeland Security.  My career has provided me with experience in a wide variety of design, manufacturing, construction, remediation, and demolition practices and equipment, process instrumentation and controls, and plant equipment.  Along the way, we moved to the country, built a beautiful farm house, and raised our kids on hard work and fresh air.  I wasn’t looking for a new job when God made it abundantly obvious that he was calling me to leave my well-paying job, dream home, and little family farm and “go to a land I will show you”.  That land was LeTourneau University in 2016, where I now have the privilege and hope of spending the last quarter of my career at this Christ-centered institution, helping the next generation integrate faith and learning here so they can integrate faith and work wherever God calls them.

My wife and I met on a summer mission trip in college and were married in 1986.  We have 5 children… our oldest is a 2013 LeTourneau graduate and he is now an air traffic controller. We have two daughters who graduated from Biola University (2015, 2018).  Our remaining daughter graduated from LeTourneau in 2019. Our youngest son graduated from LeTourneau in 2020. 

My father worked for the U.S. Forest Service and we moved every 3 years or so around the country as I was growing up.  My job involved a lot of travel, both short term and off-site assignments.  Fun fact: I have been to 49 states and 14 countries.  But we are now happy to be settled here in East Texas, where any travel is usually by our choice.
