About Doemetal

Thomas Doemetal
President & Founder


With more than 20 years of experience buying and selling spare aircraft parts, Doemetal' President and Founder Thomas brings a thorough knowledge of aviation equipment and worldwide network of aircraft parts suppliers.

Thomas received his bachelor's degree in finance from Loras College in Dubuque, Iowa, and spent a short time as a stockbroker before finding his niche in the aviation industry. It didn't take long to discover that the transition from buying and selling stocks to buying and selling spare aircraft parts was a natural fit.

He landed his first position with an aviation parts supplier in 1988. As vice president of international sales, he gained extensive experience in purchasing, shipping and receiving, and established contacts with hundreds of reputable parts vendors around the world, consistently ranking among the top sales leaders.

Building on a proven track record, Thomas fulfilled a personal goal of owning his own business when he started Doemetal, Inc. in 1996. His vision of providing customers with quality parts at a fair price, product and market expertise, and exceptional customer service is the driving force behind the company's success.
