Tri Pak's History
Tri Pak opened its doors in the mid-1980s as the Union Pacific Reload site on Portland Avenue in Tacoma, WA. with five employees. In the late 1990s, Cory and Margaret Sonnen purchased Tri Pak Uniquely positioned in the heart of the Port of Tacoma, the new owners recognized Tri Pak's excellent potential and expanded the business into the import and export of ocean containers.
The next three years were spent strategically leasing or buying rare, rail-served Port property and investing in three unique proprietary bulk conveyance systems. By 2000, Tri Pak acquired 6 locations and handled virtually any commodity passing through the Port, including bulk commodities, organic food-grade, bagged, aggregate, coils, and liquid products, machinery, and lumber. Tri Pak offered transloading and warehousing facilities for bulk grains, bulk aggregates, lumber, building material, steel and roofing, and many bulk and non-bulk materials. Tri Pak also diversified its ability to be served by all three railroads; Union Pacific Railroad, Burlington Northern Railroad, and TMBL.
