Trefethen & Co Bader & Olson

Cadogan Tate, a specialist in high-value storage and logistics for interiors and art handling, has acquired Trefethen & Co Bader & Olson, a Seattle-based firm specializing in furniture receiving, warehousing, delivery and installation. This is Cadogan Tate's seventh acquisition since being acquired by TSG Consumer, a private equity firm specializing in consumer brands. This strategic acquisition aligns with Cadogan Tate's commitment to delivering integrated, end-to-end services across art, furniture and interiors, and strengthens Cadogan Tate's position as a global provider with a physical presence in the Pacific Northwest. The combined entity will offer clients a streamlined, unified experience underpinned by domain expertise, and the operational scale to support complex, multidisciplinary projects. Whether for private residences, architectural fit-outs, galleries or corporate environments, this union allows clients to partner with a single provider spanning art handling, interiors and furniture logistics and installation services. Perkins Coie provided legal counsel to Cadogan Tate. Financial terms of the transaction were not disclosed. With almost half a century of experience, Cadogan Tate specializes in fine-asset logistics: art handling, packing, transport, storage and installation services for museums, galleries, private collections, designers and high net worth clients. In addition to Seattle, the company maintains operations in global markets, including London, New York, Los Angeles, San Francisco, Aspen, Miami and Paris.
