DDL, a third party testing lab, was founded in 1990 by John Hart, CEO, and Patrick Nolan, COO, both of which still work out of the home office, in Eden Prairie. John and Pat had previously worked for Eden Prairie based testing products supplier MTS Systems. The two started DDL (Distribution Dynamic Labs) when they discovered that their department at MTS was being divested.
