Trust in the Lord with all your heart, and do not rely on your own understanding. In all your ways acknowledge Him, and He will direct your paths.

I had the privilege of growing up in a loving Christian family and first trusted Jesus as a boy of ten. Because my father was an engineer and I was good at math I studied Electrical Engineering at the local university.  As I was approaching my senior year I wondered what direction to pursue for employment. Most engineering jobs at the time were along the lines of designing televisions or making missiles, neither of which appealed to me. When I expressed this concern to a friend, he arranged for the dean to introduce me to Wilson Greatbatch, an electrical engineer, a believer, and the inventor of the cardiac pacemaker. Wilson Greatbatch offered me the opportunity to work for his company for the summer. As a result, I applied to graduate school to study biomedical engineering, an area I was sure could benefit humankind.

During my time in grad school at Drexel University I interacted often with a Christian faculty member, Dr. Bill Graff (later my colleague at LeTourneau), who challenged my shallow thinking and got me pondering these things-

  • What really is faith? It’s not just a blind leap in the dark.
  • Is there actually a sacred-secular wall, a “two-pot system” for life, or is God is the God of all parts of life?
  • Is engineering a legitimate “calling” from God, just as pastoral ministry is a “calling” from God?

After a postdoctoral research project (working with physiology faculty studying the mechanical properties of single isolated heart cells) at the University of Kansas Medical Center, I accepted a faculty position in engineering at LeTourneau University (then known as LeTourneau College) in Longview, Texas. My wife Jani and I enjoy hiking in the National Parks and visiting with our children and grandkids. God has been faithful for all these years, and life has been a great adventure.
