HUNTINGTON, W.Va. -- Promoting STEM (science, technology, engineering, and mathematics) education is more than a passing trend for Derek Maxey and Don Whitmore, two registered professional engineers with the U.S. Army Corps of Engineers, Huntington District. Both quietly volunteer as guest lecturers at local universities, bringing their real-world experience and stories from the field to undergraduate students. Maxey, a mechanical engineer and Whitmore, a civil engineer, are committed to inspiring and mentoring tomorrow's engineers, they said.
