Jonathan Mariner, founder and president of TaxDay, a private software firm that helps people track their multi-state travel, has been named to the board of directors for Detroit’s Rocket Cos. He serves as chairman for the board’s audit committee.

Mariner’s appointment began last week. He previously served as CFO and chief investment officer for Major League Baseball and CFO of the Florida Marlins, Florida Panthers, and Dolphins Stadium.

“Jonathan has an incredible track record of driving great results for the businesses and teams he has led,” says Jay Farner, CEO. “We look forward to leveraging his experience and guidance to build on the momentum of our longstanding success.”

Other boards Mariner has served on include Tyson Foods and McGraw Hill Education. He is a senior adviser to Overtime Sports, a new sports broadcasting network focused on young, digital-native sports fans. After earning his bachelor’s degree in accounting from the University of Virginia, Mariner completed his Master of Business Administration from Harvard Business School.

“Serving on the board of Rocket Cos. is a great honor,” Mariner says. “I look forward to collaborating with my fellow Directors and bringing my background and perspective to help impact the outcome.”

Rocket Cos. recently announced it has generated $6.6 billion of net income through the first three quarters of 2020. In the third quarter alone, its subsidiary Rocket Mortgage originated $89 billion in closed loan volume, a record for the 35-year-old company.
