MILFORD, Conn. — Trevor Haynes, chief business development officer, has been named interim CEO of Subway. He will succeed Suzanne Greco, who announced she will retire on June 30.

Haynes is an experienced leader with deep knowledge of the company and has held numerous leadership roles at Subway since joining the company in 2006 as territory manager in Australia. He moved to the United Kingdom in 2009 to serve as the senior area development manager for the UK and Ireland and in 2014 joined the team in Milford to serve as the global director of operations.

He received a master’s degree in international management from Queensland Univ. of Technology.

Following her retirement, Greco will become a senior adviser to the company. She joined Subway in 1973 as a “sandwich artist” and would later spend more than two decades as part of the research and development team. She facilitated the creation of the Independent Purchasing Cooperative (IPC) in 1996 to handle the Subway brand’s product purchasing. In 2013 she was promoted to vice president of operations and research and development in 2013 and was named CEO in 2015.

She received a bachelor’s degree in business administration from Sacred Heart Univ. in Fairfield, Connecticut

“We would like to express our deep appreciation to Suzanne for her lifetime of service in building Subway into one of the world’s greatest successes,” Subway’s shareholders said in a statement. “She was there when the first sandwich shop opened, and as CEO she focused on helping the company adapt to a more competitive and dynamic environment. As we work with Suzanne on a smooth transition for the business we cherish, we are grateful for her extraordinary contributions and her insightful and dedicated leadership.  We are optimistic about the brand and look forward to working with the next CEO to ensure a robust future for the company.”

Late last month Subway announced it would shift its focus overseas and close about 500 US locations in 2018. The announcement comes after the restaurant chain shuttered hundreds of stores in both 2017 and 2016.
