Industry veterans return to bolster platform across a variety of markets and property sectors

Cushman & Wakefield (NYSE:CWK) today announced the return of three senior professionals to its Valuation & Advisory platform, including Chris Sonne, based in Southern California, Greg Becker, MAI, MRICS, based in Tampa, Florida, and Chris Lassiter, based in Nashville, Tennessee. All return as Executive Directors, expanding Cushman & Wakefield’s presence across Southern California and the Southeast.

"The return of Chris Sonne, Greg Becker and Chris Lassiter is a testament to the momentum of our Valuation & Advisory business and our continued investment in strategic growth," said Erick Mazzoni, U.S. Market Lead for Valuation & Advisory at Cushman & Wakefield. "As client demand evolves, we are focused on expanding our capabilities, deepening our coverage across key markets, and attracting proven professionals who will help drive the next phase of growth for our platform."

Sonne returns from Newmark, rejoining Cushman & Wakefield’s national self-storage practice. A leading authority in institutional self-storage valuation, he also brings his two-person team to the firm, bolstering coverage across a sector that continues to see steady institutional demand in the booming Southern California market.

"Chris is one of the most respected voices in self-storage valuation," said Tim Garey, Managing Director and Practice Lead of Cushman & Wakefield’s Valuation & Advisory National Self Storage Group. "His track record, client relationships and the trust he has built across the institutional landscape are unmatched. Bringing Chris back immediately strengthens our ability to advise on the most complex self storage assignments nationwide."

Becker brings more than 35 years of experience valuing complex industrial, retail, office and special-purpose assets throughout the Southeast and Caribbean. Over his career, he has completed assignments across 43 states and most Caribbean nations, including major industrial portfolios, leading retail centers, and large-scale resort and marina assets. He rejoins from Colliers.

Lassiter returns as Tennessee Region Lead, specializing in multifamily assets. He brings experience across a range of property types and plays an active leadership role within the Appraisal Institute’s Tennessee chapter. He most recently served at Apprise by Walker & Dunlop.

"Greg and Chris each bring deep expertise and strong client relationships that are critical to our continued growth across the Southeast and Tennessee," said Dave Beshears, Southeast Market Lead for Valuation & Advisory at Cushman & Wakefield. "Greg’s experience across complex asset classes throughout the Southeast and Caribbean is exceptionally rare, and Chris’ leadership in Tennessee further advances our multifamily capabilities in one of the country’s most active markets."
