PSSI-Building-for-History-Page

From our humble beginnings in a market segment that barely existed, to a high performing organization larger than all of our competitors combined, our culture of being entrepreneurial, hard working and finding the best solutions for our customers has not changed.

1973- PSSI was founded in Mt. Pleasant, Iowa by Tom Turner who was employed by Bonewitz Chemical at the time. Tom idea was to provide contract sanitation services using a non-unionized work force. His first plant, Illini Beef in Joslin, IL, is still one of PSSI’s customers today (It is now owned by Tyson Foods).
1977- As the organization grows, Tom’s close friend, Warren Dusenbury, sees potential in the business and buys him out. Warren folds PSSI into his parent company, the Chemidyne Corporation. In addition to PSSI, Royal Chemical is also managed under the Chemidyne umbrella. Warren was the president of the Chemidyne Corporation from 1966-1988. Warren ran all three companies successfully until 1988.
1983- Combining Chemidyne’s chemical products with PSSI’s services gave them a competitive advantage in the Contract Sanitation market. By 1983 PSSI was cleaning 25 plants and was employing between 1,000 to 1, 500 employees.
