Dr. Jim Winchester, Owner and President, is the hands-on manager of all aspects of Eon’s operations. As a senior aerospace executive at Teledyne, Litton, Northrop Grumman and L-3 Jim learned and refined the necessary skills and processes to engineer, manufacture and support what customers need, not just generic off-the-shelf LRU’s. Eon partners with our customers to deliver end results. Eon will often invest its internal R&D funds to create or tailor existing hardware and software to create unique products or systems. The key ingredient of Eon is a mix of carefully selected staff of technical, manufacturing and business development specialists, adept at working as a team.   That team has driven Eon revenues to grow 20% per year since 2016.
