E-Source began in 1993 while current E-Source President/CEO Harry Starkweather was the southern region sales manager for InterMetro Industries. While at InterMetro, he hired Mary Lee Cruz (current CFO/Principal) and Chris Barta (current Principal/Sales Rep) as regional territory managers. Their collective efforts placed the north Texas territory as the national sales leader. As InterMetro made the transition to all manufacturers reps, the brand was offered to this successful team as their first product line and the beginning of what constitutes present day E-Source.
E-Source is now one of the largest manufacturer's agents in the United States, only representing lines of the highest quality. The current E-Source headquarters in Irving, TX features a test kitchen, a full bar, and a conference center.
