Knight Frank has appointed three partners, three associates and two senior surveyors as part of a strategic expansion to its valuations business.

Gavin Spreyer has joined the team as a partner, having spent almost 20 years at Cushman & Wakefield (previously DTZ). Gillian Bowman, who similarly focused on valuations in her previous role at BNP Paribas, has also been appointed partner, with specific focus on the retail sector.

Karen Callahan, partner, has joined the hotels team, having previously worked for Dolce Hotels & Resorts, who have more recently become Wyndham Hotels & Resorts. All will report to global head of valuations, Rupert Johnson, and assist with further growth of the valuations business, now totalling some 180 people across the UK.

Joining as associates are Isma Ali, Alistair Johnstone and Will Garner. Garner returns to Knight Frank after a sabbatical slotting back into his previous role, assisting in loan security and fund valuations in the City. Ali and Johnstone both joined from CBRE, and will be focusing on retail valuations and Central London commercial valuations respectively.

In addition, two senior surveyors, Matthew Dichler and Shrav Khera have joined. Khera, from BNP Paribas, will focus on portfolio valuations, reporting to Michael Crowe - while Matthew, from Colliers in Dubai, where he was a senior valuer, will be working on valuation of portfolio assets.
