Newmark has appointed Sebastian Wallis as a senior leader in its UK valuation team.
Wallis, who more than 25 years of experience in the UK property industry, joins Newmark from a private office where he served as a senior consultant.
Prior to that, he led CBRE’s London residential valuation team and was a partner at Knight Frank, where he led the firm’s London residential development valuation team for more than a decade.
Jonathan Godfrey, head of UK valuation at Newmark, said: ”Sebastian’s reputation precedes him. He is a recognised authority in London’s residential markets and brings deep technical expertise, a sharp strategic lens and long-standing relationships with some of the industry’s most influential players. His addition reinforces our commitment to growing our UK offering with top-tier talent who deliver clarity and confidence to clients navigating complex property decisions.”
Wallis added: “Joining Newmark presents an exciting opportunity to contribute to a growing, ambitious platform that values precision, insight and long-term client relationships. I’m looking forward to helping strengthen the firm’s presence in the UK residential market and collaborating with clients on their most high-profile and complex valuation needs.”
