OUR STORY
HUMBLE BEGINNINGS
Korte & Luitjohan Contractors, Inc. (K&L) is a family-owned general contractor in Highland, Illinois. We offer design-build, construction management and general contractor services throughout the St. Louis Metro East and Southern Illinois.
In 1958, Cyril B. “Pete” Korte established the company when he borrowed $500 from his father-in-law to buy a rubber-tired trencher. He began installing gas services for Illinois Power in the City of Highland. A year later, Pete’s brother-in-law, Joe Luitjohan, joined him in the underground utility business. For 23 years, the company grew as a dependable underground utility contractor.
In 1981, Pete bought Joe’s interest in the company and K&L began working in the heavy construction market. Ever growing and ever mindful of opportunities in the construction market, Korte & Luitjohan Contractors steadily expanded its scope in three major construction markets – building, heavy and utility
