Shane Stringfellow
President
Shane Stringfellow is the president of Jetraxx and the architect of its revolutionary approach to aviation asset management. He also serves as executive vice president for technical services for Jet Engine Solutions (JES), the company that inspired the creation of Jetraxx.
With more than 20 years of hands-on experience with aircraft maintenance, Shane appreciates the importance of thorough records management throughout the life of a leased asset. From this experience—managing paper-based maintenance records that were too easily lost, damaged, or rendered illegible—he developed a role-based system to digitize, track, and automate documentation for engine lessors and lessees. What began as an in-house system for JES quickly grew into a product for the broader aviation market and a new company: Jetraxx.
Shane’s love of aviation took him first to the U.S. Air Force, and later, to GE Aviation, where he served as director of quality and technical services, and to CT Aerospace, where he served in multiple roles, including director of operations. During his time at GE Aviation, he met his future business partners, Brian Biersdorfer and JD Diwan, and the three became fast friends. Years later, when Brian and JD started JES, they recruited Shane to manage technical services.
From his Air Force service, Shane developed a commitment to excellence in execution and discipline—forces that continue to shape the culture of Jetraxx. Equally important to Shane is that employees experience a sense of comradery, shared purpose, and take pride in a job well done. Jetraxx actively hires veterans from across the services, providing post-military career opportunities to those who have served their country.

Vice President
Jamil “JD” Diwan
Vice President
Jamil “JD” Diwan serves as vice president for Jetraxx, overseeing sales and marketing activities, and leading big-picture planning for the company. JD was a founding member of the leadership team for Jet Engine Solutions (JES), the company that inspired the creation of Jetraxx, and continues to serve as its president and managing director.
With more than 20 years in the aviation industry, JD began his career at GE Aviation, working his way up from technician and inspector to running day-to-day operations for the commercial aircraft engine hospital shop and field team. At GE Aviation, JD had hands-on experience with most of the major domestic and international carriers, involved in all aspects of engine repair and maintenance.
JD’s passion for aviation was sealed with his first work assignment—a 727 for UPS. As someone who had always loved airplanes, the opportunity to climb on and around a plane was a dream come true. But as much as he loved working on planes, doing flight controls and participating in flight tests, it was the engines that captured his heart.
It was during his time as an engine specialist that the idea for JES was born. Working alongside future co-founder Brian Biersdorfer, JD saw an opportunity in an underserved market—leased engine maintenance and repair. Compared to the big airline customers, leased engines had lower financial returns, meaning they would never be prioritized in the current service marketplace. With Brian’s knowledge of the leasing market and JD’s experience managing the hospital shop and field team, they created JES.
JD received his FAA A&P certificate in aviation management from Everett Community College. He still loves the sound of a plane passing overhead—when instinct kicks in, he can’t help but identify the engine and mentally assess its condition as it goes by.

Brian Biersdorfer
Vice President
Brian Biersdorfer is vice president for Jetraxx, where he is a key member of the leadership team. Additionally, Brian serves as executive vice president and director of operations for Jet Engine Solutions (JES), the company he co-founded that inspired the creation of Jetraxx.
Brian’s career in aviation began as a jet engine technician in the U.S. Air Force. Because of his service and belief in supporting veterans as they transition into civilian life, Jetraxx and JES actively recruit former members from all branches of service.
With his hands-on engine experience, Brian was a natural fit for GE, first as an assembly and test technician for GE Aircraft Engines, then as a customer service planner for GE Aviation. It was there that he met his future business partners, JD Diwan and Shane Stringfellow.
While overseeing a leased engine repair group, Brian’s technicians were frequently tapped to work on the big airline customers that brought larger financial returns. Brian saw an opportunity in an underserved market—leased engine maintenance and repair. With Brian’s knowledge of the leasing market and JD’s experience managing the hospital shop and field team, they created JES.
Brian earned his degree in aerospace science from Embry-Riddle Aeronautical University. His grounded, no-nonsense approach provides a solid foundation for the growth and success of the businesses he founded.
