About Theochem Theochem was founded in 1963 by Speros P. Theofilos, who believed in the American dream and the future of custom packaging and the private labeling of quality cleaning and sanitary maintenance products. What originally started in a 1000Sq.Ft. building In Ybor City, Florida grew ten fold within a few short years followed by numerous acquisitions. These early acquisitions not only created the foundation for our current product groups, but also positioned the company for years of innovative and profitable growth designed to make our maintenance programs efficient, cost effective and in total compliance. Theochem Today... Today, Theochem Laboratories is a totally integrated company in North Tampa which houses our corporate office, a state-of-the-art liquid and powder..
