Pho, the Isis Equity Partners-backed Vietnamese fast-casual concept founded and led by Stephen and Juliette Wall, has strengthened its operational team as it gears up for its next stage of growth. The seven-strong group, which hopes to grow its estate to up to 25 sites over the next four years, has promoted Ewan McDonald and Anna Iskra to operations managers after the departure of operations director Tim Mills earlier this year. Mills had been with the group for just over a year and a half and was formerly head of operations at Paul UK Stephen Wall told M&C Report that the group was delighted to be able to bring new talent through the company, who already “understand the group’s DNA”. He said: “After the link up with Isis we are spending the next few months putting the team and structure in place for our next stage of growth. We hope to have a chairman in place by the turn of the year and I am currently working on our pipeline for the coming 12 months.” Isis has invested £5.2m in the chain, which was founded by the Walls in Clerkenwell in 2005. The investment is set to aid the chain’s growth in London and the regions. It currently operates six restaurants in London, after opening on the former S&M Cafe site in Spitalfields in August, plus its biggest outlet, a 130-cover restaurant in Brighton. The group will continue to concentrate on expanding in London initially, but hopes to eventually expand into further regional locations like Brighton, such as Oxford, Cambridge, Leeds and Bristol.
