Antidote Computer Services was founded in 1997 by Paul Swarthout. Mr. Swarthout got his start in the computer field with the help of a Bachelor of Science degree from Bradley University, in Peoria, IL many years ago. Swarthout has worked for some of St Louis' premiere employers developing software and maintaining computers. Further, Swarthout has worked as a software developer and database expert in Chicago and Los Angeles.

Prior to founding Antidote Computer Services, Swarthout gained experience working in the defense industry, the entertainment industry, the software development industry, the petroleum industry (a favorite of his), and the transportation industry. Since founding Antidote Computer Services over 11 years ago, Swarthout has had the privilege to work with customers in the construction industry, the insurance industry, the software development industry, the entertainment industry, housing, manufacturing, retail sales, the field of medicine and many others.
