Sam got his feet wet with JLDTS as an intern in his last semester of school before joining full time in January of 2020.

Sam is a University of Kentucky Alum with his BS in Biosystems and Agricultural Engineering and Master’s in Business Administration. In his time as a student, he always found himself gravitating towards programming and automation which lead him to a research position surrounding vehicle networking and microcontrollers. Following his desire to be equipped for any opportunity, Sam completed his MBA in an accelerated program before returning to his engineering roots.

Sam is a follower of Christ, husband, son, and brother. He enjoys spending his free time doing anything outside. Sam grew up at the pool where he learned there is no substitute for determination and hard work.
