Scott Jones

The pragmatic, knowledgeable leader is recognized by colleagues for his "ability to see the big picture and keep organizations moving forward in a positive direction." In addition, his degree in Finance from Stephen F. Austin State University has established Scott as "one of the lucky few who has in-depth knowledge of both finance and operations."

Leon Johnson

Leon's reputation as the guru of learning management began as co-founder of Capstone Engineering more than 15 years ago. There, he designed an innovative training and development program that was based on demonstrated performance rather than the traditional "time in grade" systems. His successful approach reached beyond his employees to the training programs of his clients. Since leaving Capstone in 2010, Leon has remained focused on the arenas of training and personnel development as a consultant and learning manager. In addition to his degree in Industrial Engineering, he is a licensed teacher in the State of Texas and a Certified Professional in Learning and Performance (CPLP).
