ESS Companies Welcomes Monks Construction

We are proud to announce that Monks Construction, based in Colorado Springs, Colorado, has officially joined ESS Companies! As a major infrastructure contractor across the Western Region, Monks adds valuable depth to ESSC’s regional capabilities, particularly dam and energy infrastructure expertise.  

“We’re thrilled to have Monks join ESS Companies,” said Robert Gillis, ESSC co-chief executive officer. “Their exceptional leadership and strong, people-first culture made this a natural fit. Adding these roots in Colorado will provide shared resources and support our vision for the future.” 

With the addition of Monks Construction, we are excited to bring more than 150 new employee-owners on board. This expansion strengthens our geographic reach and diversification. Just as important, Monks shares our dedication to protecting people and prioritizing safety in every aspect of the job. Though we are all employee-owners together, Monks will continue to operate independently. 

“Our team at Monks has become a Western Region leader in our industry and built a tradition of safety, quality, and respect on all of our projects,” said Jason Greer, Monks’ president. “We’re thrilled to pass the legacy to our employees through the [ESSC ESOP].” 

This transition is more than just adding a new team — it’s a commitment to shared success, accountability and long-term commitment. We are excited to extend this opportunity to Monks Construction.
