WHEELING, IL (AUGUST 6, 2025) – Three experienced aviation professionals have joined George J. Priester Aviation leadership team as the private aviation services company strengthens its maintenance operations and customer services.
Eric Bewersdorf, who joined the aircraft management and charter company last year, serves as Vice President of Maintenance, while Alan Harman, Director of Maintenance, and Alexandra Guras, National Director of Flight Services, recently came aboard.
“Eric, Alan and Alex are great examples of how George J. Priester’s family-owned legacy and customer-first culture help attract leaders who share that commitment to client service,” said Brent Moldowan, President & CEO of George J. Priester Aviation. “They’re helping implement processes and management that continue to raise our standards even higher.”
In overseeing the company’s maintenance control department, Bewersdorf has been utilizing his 25 years of OEM experience, and new technologies are maximizing efficiencies for managed-aircraft owners and fleet operators. In addition to his aircraft manufacturer experience, he also has coordinated maintenance and delivery for a large Part 135 fleet. The Michigan-based executive started his aviation career working as a part-time mechanic as a teenager and is now involved with career development initiatives through the National Business Aviation Association to introduce students to technician careers within corporate aviation.
Harman has been hands-on in aircraft maintenance and quality control management since his service in the U.S. Army ended more than a decade ago. He maintained a 75-aircraft fleet for a national Part 135 operator, as well as a regional private aviation provider before joining George J. Priester, where he will be based near its Chicago headquarters. Harman combines his deep mechanical expertise with a passion for historical military aircraft. His commitment to excellence and innovation will drive the company’s continued advancement in technology and operational excellence.
Based in Colorado, Guras has a strong background in aircraft management and dispatch operations, with a proven track record for elevating service standards across customer-facing, scheduling and sales teams. Her focus on exceeding client expectations has shaped high-performance support environments throughout her career. She has overseen air medical bases, managing performance, compliance and service delivery in high-pressure environments, which aligns with George J. Priester’s affiliation with Flight for Life at its Mayo Aviation location. She is the President and Chair of the Colorado Aviation Business Association where she advocates for industry collaboration, growth and education.
The company, through its three brands of Priester Aviation, Mayo Aviation and Hill Private Aviation, has nearly 90 managed aircraft and provides tailored support in crewing, flight operations and maintenance coordination, among other personalized services.
