UPS Freight President Jack Holmes has announced his retirement after working for the company for 37 years, the company announced.

Holmes’ retirement is effective June 30. He will be succeeded by UPS Mid-Atlantic District Manager Rich McArdle in June.

In addition to his duties at UPS Freight, Holmes serves as the co-chairman of the National Freight Advisory Committee’s Conditions, Performance, and Data Subcommittee and sits on the board of directors of the American Transportation Research Institute.

Holmes joined UPS in 1979 as a package handler in Philadelphia. He later became a package car driver and was eventually promoted into management. He served in a variety of operations and transportation management roles before rising to his current position in 2007.

“Jack's contributions to UPS and the trucking industry are immeasurable,” said Myron Gray, president of U.S. operations for UPS. “His strong leadership, deep industry knowledge and professional counsel have educated and inspired countless UPSers and others who have worked with him throughout his career.”

McArdle started at UPS in 1982 as a part time employee. In 1985, he was part of the UPS team that initiated international air service between the U.S. and Europe. McArdle went on to develop plans for further expansions to Canada, Japan, Southeast Asia and Central America. After various operations assignments, McArdle was promoted to South Carolina District Manager in 2007. In 2010, he began an assignment in UPS’s public affairs office in Washington, D.C., before taking on his current position as Mid-Atlantic District Manager in 2015. McArdle has a bachelor's degree in finance from the University of Louisville and a master's degree in management from Webster University.
