Tangram Onsite

We offer a wide variety of services including refinishing, reupholstering + cleaning.

Onsite was founded in 1984 by Mitchel Zelinger, Tangram’s VP of Business Development, and his dad, Hugo, as an onsite, one-stop-shop commercial interiors cleaning service; hence the name, Onsite. At this time, Onsite was operating out of a converted barbershop in the Pico-Robertson area. In 1998 with 74 employees operating out of a 32,000 square foot facility in Downey, Onsite was acquired by Pacific Business Interiors. Two years later, PBI and CBI (California Business Interiors), the two largest dealers in the Southern California market at the time, merged to create Tangram and the expansion continued. Tangram Onsite has proudly maintained our mom and pop shop feel throughout all the years of growth and most of our employees as well.
