Meet the Jesik Team
Jesik was formed in 2005 by Andy Jesik, with years of experience from projects in the western U.S., Peru, Mexico, Colombia, and Africa from large new copper, gold, and phosphate mines. These projects included pipelines, ports, dams, reservoirs, roadways, and processing plants. Initial capital investments varied with the largest over 1 billion US dollars.
Andy leased a small office in 2014 where he was born and raised, Pueblo, Colorado. A soils and concrete testing laboratory was established, and we pursued work in Colorado, New Mexico, and Arizona. We outgrew our space, and our team designed an office, laboratory, and garage that was constructed at 800 W. 8th Street in Pueblo, Colorado. The building was completed in the spring of 2022.
Jesik employee’s became owners of the company in 2021 to reward our dedicated professionals who take pride in their work and maintain a high customer service standard.
We serve our clients and communities by listening, then we plan, design, and engineer solutions that improve lives, and livelihoods, and create sustainable legacies for generations to come.
During construction, we provide quality control and assurance services, to confirm materials and workmanship meet the project plans and specifications. Laboratory testing is completed on construction materials in our AASHTO/CCRL accredited laboratory and on-site testing, and inspections are completed with our experienced, certified staff.
