Pho, the Vietnamese fast-casual concept, has appointed Tim Mills, a former Paul UK executive, as operations director - a newly-created position for the growing group.

He joins the group, which is led by entrepreneurs Stephen and Juliette Wall, as it prepares to expand materially over the next three-to-five years, primarily in London. It has just opened its fifth site in London’s Wardour Street, Soho.

Mills was previously head of operations at Paul UK, helping it to grow to 20 sites, and has also worked at Carluccio’s and Krispy Kreme.

Pho, which is based on the Vietnamese national dish of noodle soup (pronounced “fuh’), has four locations in London plus one in Brighton, its biggest with 130 covers. The Wardour Street venue has 60 covers.

Stephen Wall said the appointment of Mills was a central to the company’s plans to accelerate its openings.

Pho is backed by ETM Group, the food-led London pub operator led by Ed and Tom Martin, which has a 50% stake.
