YOUR COMMERCIAL CONSTRUCTION PARTNER
Our experienced team plans your build for lasting durability and sustainability.



Championing Intentional Design Since 2002
Since our start, we have had the honor of working on hundreds of commercial construction projects in and around Colorado.
What others have said…
“We are new to the construction world and had a lot of questions. It was so nice to discover that we had a trustworthy team in Aslan Corporation. The whole team truly feels like part of our family. It’s clear that Aslan Corporation is passionate about their work and making sure their clients are satisfied. Not only would we recommend them, but we also hope to work with them again ourselves!”
“Throughout our collaboration, Aslan’s team, led by Peter Chapa, consistently demonstrated exceptional thoroughness, extensive knowledge, and a high level of professionalism. Their ability to plan and execute each phase of my project significantly contributed to its successful and timely completion.”
“Thank you for your vision, your leadership, and your integrity. In these turbulent times, it’s difficult to find contractors who say what they are going to do, and then do what they say, even when it has a negative impact on their profits. Aslan Corporation is the kind of rare company that I will tell anyone about who will listen.”
“Aslan has unparalleled experience, tenacious execution, and their subcontractors know their craft very well. They would regularly come in ahead of schedule, under budget, and added considerable value engineering on every job. Their communication was timely and professional, and if a problem came up, they would find and execute a solution instead of blaming others.”
“Aslan continued to find ways to optimize the construction timeframe and save us money during the construction process. Aslan’s team were transparent with issues that arose and were aggressive in seeking solutions to the inevitable challenges that arise during the construction phase.”

It all started in 2002.
That’s when our founders John and Aaron Voorhees, a father-son duo (as well as third and fourth generation contractors!), set out to bring integrity, quality, and imagination to commercial building projects in Colorado.
Since then, we have expanded to position ourselves on the leading edge of energy-efficient construction, proudly serving Colorado and surrounding areas. (See the specific areas we serve here.)
The work we do is an honor, and it all comes down to our people. We wouldn’t be here without the expertise, commitment, and passion from every person on our team.
