Steve GilbertEngineering Manager at CTC

“CTC has been working with Elite Underground since 2007. It has come to be a great working relationship over the years. Elite handles our maintenance contract, which includes anything from changing out a pedestal to a multi-mile cable installation or new subdivision build-outs with copper and fiber facilities. With Elite Underground, no deadline is too short, no job is too big, and “no” is never an answer. Their hard work, dedication and commitment to a quality product is second to none. Being a growing cooperative, we have a lot of changing needs and Elite Underground meets all of those needs in stride. I look forward to working with Elite Underground hopefully for years to come.”.

He is always willing to work with our crew to make sure our project is successful. I look forward to our continued relationship.

“Eli has been a leader in helping us deliver broadband to unserved areas. In 2015 Elite’s crew helped us hook up over 200 unserved homes that did not have Internet access. He was able to accomplish this through many obstacles, including one of the worst storms our area has ever experienced, all while completing the project on time and on budget. His dedication to the project changed the lives of many people who were ecstatic to finally get high speed Internet. Eli and his family truly care about helping others, whether it’s through delivering much needed broadband services, or through his ongoing philanthropy to nonprofit organizations and the Brainerd Lakes Chamber of Commerce.”
