What started as a small company in a nonexistent market has blossomed into a high-performing organization larger than all of our competitors combined. Yet through all the change, our entrepreneurial culture and commitment to serving our customers has always remained the same.
PSSI is founded in Mt. Pleasant, Iowa by Tom Turner, who had a vision of providing contract sanitation services using a non-unionized workforce. His first plant, Illini Beef in Joslin, IL (now part of Tyson Foods), is still one of our customers today.
PSSI merges with Chemidyne Corporation after Tom’s close friend, Warren Dusenbury, sees potential in the business and buys him out. Warren also brought Royal Chemical under the Chemidyne Corporation umbrella, and ran all three companies successfully until 1988.
The competitive advantage of combining PSSI’s services and Chemidyne’s chemical products was yielding strong results, cleaning 25 plants with over 1,000 employees.
PSSI is sold and is purchased by Dan Zelman and three other investors. Dan becomes CFO of PSSI, beginning a period of immense growth over the next decade, including the addition of accounts like Cargill, Hormel and American Food Group.
