Mark David Hemingway

I was saddened to hear of Mark's passing but joyful to know that his faith in Jesus Christ has promoted him to heaven! We'll meet again. Mark and I both worked for AC Sparkplug then Delphi Engineering where our activities crossed paths every so often. He was very technology oriented and would tell me about his current project(s). May God be a source of comfort and strength to his family during this time of sorrow.

Cyndi and Adam were plum tuckered out! I was single at the time and always enjoyed hanging out with such a loving family Picture 2: This was one of...

I met Mark Hemingway in 1988 at AC Spark Plug. My first task was to learn the job (vehicle systems work to validate catalytic converter durability) by working closely with him. Mark´s welcoming smile, humble attitude and creative, teaching approach to technical details made it a great experience. I soon learned Mark had specific skills for our exhaust systems work, beyond anyone else around. His patience and good humor while I was learning made ALL THE DIFFERENCE in learning a lot, and I...
