Ryder appointed John J. Diez to the role of executive vice president and CFO. Diez will succeed Scott T. Parker, who resigned from the position to pursue other opportunities and will remain with Ryder through June 4.

Diez, most recently president of Ryder’s fleet management solutions (FMS) business, will oversee all of Ryder’s financial management functions, including finance and accounting, treasury, tax, audit, corporate strategy, and investor relations.

During his 20-year tenure at Ryder, Diez has held a variety of senior operational and financial management roles with increasing responsibility. Prior to serving as president of Ryder’s FMS business, he was president of the company’s dedicated transportation solutions (DTS) business unit. In addition, Diez served as Ryder’s senior vice president of field finance, CFO for the FMS business segment, senior vice president of asset management and assistant controller for the company. Prior to joining Ryder in 2002, Diez began his career in the audit practice of KPMG. Diez is a licensed certified public accountant.

As part of this organizational change, Ryder named Tom Havens president of its fleet management solutions business unit. With this promotion, Havens will join Ryder’s executive leadership team and report to Robert E. Sanchez, chairman and CEO for Ryder.

Havens is a 28-year veteran of Ryder. He was most recently senior vice president and global chief of operations for the FMS business, starting in that role in 2012. Over the course of his Ryder career, he has held a variety of positions of increasing responsibility, including head of operations for Ryder’s west region, general manager for FMS in Canada and vice president of asset management and vehicle sales, along with multiple positions in the rental organization, where he started as a rental representative in 1993.

“I am pleased we were able to fill these critically important and strategic roles with extremely talented business leaders from within the company,” Sanchez said. “Both John and Tom have strong track records in understanding the unique needs of our company while delivering transformational finance and business performance results.

“On behalf of Ryder, I would like to thank Scott for his passion and drive for our financial performance, positioning us well for the future. We wish him all the best in his future endeavors.”
