Derry, who is also Chairman of pub and brasserie group Heartwood Collection, will work with the seafood company, which operates three restaurants in London and an online fishmonger delivering fresh seafood nationwide to consumers, as well as two wholesale depots located in Brixham and Billingsgate.
"Mark has opened almost as many restaurants as we have opened oysters over the years, but more importantly, he is as passionate about great seafood and great teams as we are," says Wright Brothers co-founders Ben Wright and Robin Hancock.
"Celebrating our £30m turnover milestone seemed like a great time to get Mark on board and it's a privilege to be sharing the next stage of our seafood journey with him."
Derry opened 50 Loch Fyne seafood restaurants, which were sold to Greene King in 2007, and in 2019 was appointed non-executive director at The New World Trading Company.
“I remain fascinated by the seafood market and was delighted to discover the team at Wright Brothers share common values," he says.
"It is a unique business with a great following, and I am hugely looking forward to getting involved.”
