About Us

Wacco, Inc. was founded in 1967 when Mr. Stan Clary, owner of Process Engineering & Sales, and Mr. Robert Wise, owner of Robert W. Wise & Associates, merged the two companies to form the Wise and Clary Company, Inc. or Wacco, Inc. Located in Spartanburg, South Carolina, Wacco Inc. offered four product lines geared towards the booming textile industry in upstate South Carolina their first year in business. During the 1970’s and early 1980’s, the textile industry continued to grow and so did Wacco, Inc.

After starting the company in 1967, Mr. Wise retired in 1990 and Mr. Clary was also looking to retire. In 1993, three Wacco, Inc. employees, Maxine Casey, Jerry Koon and Stan Williams bought into the company and Mr. Clary retired in 1995.

Stan Williams joined Wacco, Inc. in April of 1992 after serving eight years in the United States Air Force. Stan is Wacco’s in house electric heat trace engineer and he also serves as Wacco’s President.
