COLTON, Calif. — John Landherr has joined A-Z Bus Sales as president.

Officials said Jim Reynolds will continue as the CEO, but he has given up his role as president to concentrate on mergers and acquisitions activity, line extensions for current business units and new business development, such as the addition of the E-One emergency vehicles product line in California.

Landherr brings over 20 years of experience in senior management roles, most recently as president of Certified Aviation Services, where he led a team of employees in growing the company from a regional provider to one with international reach and also increased sales by more than four times its annual level.

"We are excited to welcome John to the A-Z Bus team," Reynolds said. "John brings considerable experience in developing and executing business strategies that drive profitable growth across multiple markets. His experience will be invaluable as we continue to grow in our respective market verticals and strive for continuous improvement."

Landherr holds an MBA in finance from Texas A&M University and a bachelor’s degree from the United States Naval Academy.
