Hertz Corp.-owned Donlen will begin its 50th year celebration with several events that coincide with the NAFA Institute and Expo from April 8-11 in Minneapolis, Minn.

Founded in 1965 by Don Rappeport and Len Vine, Donlen started as a family-run business that focused on customer service and fleet productivity — two guiding principles still at the forefront of Donlen's philosophy.

Today, Donlen is part of the Hertz family of companies with more than 300 full time employees, providing a full range of personalized fleet management services. Leading regional and national organizations have recognized Donlen's workplace excellence, and its innovative technology sets the standard for fleet management productivity and integration.

"Everyone at Donlen is incredibly proud of achieving this milestone," said Tom Callahan, Donlen's president. "Over the years, we never lost sight of what's truly important, our customer relationships."

"Our customer-centric focus is in our DNA, and will remain so," Callahan added. "Our focus on customer service and innovation is why we've experienced incredible organic growth over the years. We've built deep and lasting relationships with our customers and we're privileged to have a highly committed and knowledgeable workforce. These core principles will carry us well into the future."

Donlen will host events coinciding with the NAFA event, such as the launch of the latest version of FleetWeb, its award-winning fleet management platform.
