He will take over from interim chair Laurence Overend who came in last month when Richard Pym resigned after less than four months in the role.
Pym took over at the financially-troubled fan-owned club following Nick Hawker’s resignation last June.
Exeter have been forced into job cuts and had to go to owners the Exeter City Supporters’ Trust for loans of around £600,000 to stay solvent earlier this season after an overspend in the last campaign.
Last week, Overend said the club would be solvent for the start of next season although the playing budget is likely to be cut.
Also set to join the board in May will be David Lee, who served a similar role between 2013 and 2020.
