Greiner Electric's work on the Hotel Polaris & Visitor Center at the Air Force Academy in Colorado Springs earned an AGC ACE Award in 2025. General Contractor DPR recommends Greiner Electric "without reservation for future projects" thanks to the Hotel Polaris experience:
Sam Garcia
Senior Project Manager, DPR Construction
Brinkman Construction partnered with Greiner Electric for the electrical scope of work on the Eating Recovery Center project in Denver, CO. Greiner Electric was brought into the project during the preconstruction process to assist as a proactive team member in the initial planning and value-analysis stages of the project. When project design requirements changed mid-project, Greiner moved quickly to replace and modify impacted areas, find creative solutions, and work with other trades to keep the schedule progressing. Close coordination was required to meet the demanding schedule and execute the project successfully. The Greiner team was professional, responsive and collaborative. They are a trusted partner for Brinkman Construction, and we value our relationship with them.
Aubry Teeters
Project Executive, Brinkman Construction
Greiner Electric has been a trusted contractor on many of our projects and we have enjoyed our working relationship. This project included a high level of detail on multiple levels, and we knew that Greiner would rise to the challenge, perform & deliver. Greiner was a major partner during the design and modeling phases of the project coming to the table with collaborative ideas to overcome constructability issues. Then on the operational side of the project, they met the challenges of putting the ideas that were conceptual into life through their construction teams actions in the field. As the schedule progressed and the project changed, the Greiner team was adaptable and was able to assist in keeping the project on track with the originally planned timetables. They helped the project keep a united front and worked in partnership with other trade partners constantly keeping the project and owner’s best interests at the for front of every decision. The Greiner Team was motivated and collaborative during the course of the project. I look forward to additional partnerships with them on more projects in the future

Greiner Electric was proactively participatory in critical design phase activities. Their involvement in design meetings early on, and their willingness to work through fair, transparent lighting pricing (often a sticking point that yields vague VE “equal” packages of dubious value) meant that the design team’s intent was delivered for lighting. It is with pleasure that we commend Greiner Electric for their diligence in lighting and controls services from preconstruction through installation on the Ent Headquarters, and we look forward to our next collaboration with them to achieve outstanding results for our clients.

I have worked with Greiner Electric for the past 18 years on multiple types of projects. Simply put, Greiner is a proven expert in preconstruction and operations. My trust in their expertise is second to none. Anytime there is a complicated or complex project to build, I think of Greiner Electric to fill that role.
