The Sonne Group Inc. and its subdivision, Self Storage Economics, will officially merge into Cushman & Wakefield on July 1.

The Sonne Group Inc., a real estate appraisal and consulting company, and Self Storage Economics (SSE), a division of Sonne Group that specializes in self-storage data, research, market reports, feasibility, valuation and consultation, will merge into Cushman & Wakefield (C&W) effective July 1. The company’s owner, Christian Sonne, has been named managing director within C&W’s Valuation Services, Self Storage Practice Group; and his entire staff will become part of the C&W team.
