About Semper EnvironmentalWho we are and What we do
Get to know our talented team and learn more about Semper Environmental’s mission.
In Latin, “semper” means always.
When we started this company in 2017, we molded our mission and mindset around this idea. “Always” means consistency and reliability, and our team remains consistent and reliable in every aspect of our work — from our conduct to our project execution.
We respond with science-based, innovative, and exceptional performance to achieve each client’s goals. We help our customers by bringing a deep engagement and commitment to every project. Our approach to explore, investigate, comprehend, and communicate all aspects of a project leads to a higher level of understanding for all stakeholders, resulting in cost savings through conflict-free progress and concurrence.
This has not gone unnoticed. Our client and teaming partners have experienced the “Semper Difference,” because we make every client feel like they’re our only client. That is what “always” means to us — always supporting our clients and always solving their tough problems.
The Semper Difference
Bart, this [UDEQ approval] letter was received today. A big thanks to Jeff and his team for getting this done. What a huge accomplishment.
BTW had my quarterly status call with the COR this week and she commented on the OUTSTANDING job by the Semper team with the door to door effort. They are so happy with the response and this extra effort was really important to them with the EPA and UDEQ more involved this year with the VI sampling.
Semper has recently completed projects with AOR International and we would gladly work with them again. Their work is efficient, detailed, and of high caliber.
Great team! EPA and Weston oversight field manager very impressed with team and quality of work….it’s great to have EPA and Weston trust on this. Gave you and Semper high praise for the team you put together.
