Doing the Right Thing - Always

What Our Clients Say

When JHL was brought to the team, they immediately immersed themselves in the project, attended every team meeting with multiple team members, and had a solutions oriented approach. JHL does an excellent job in maintaining the budget in an organized fashion and are incredibly responsive with any request we make. JHL’s open book approach certainly has fostered a strong relationship of trust over the years.

Dave Schunk, The Denver Rescue Mission

I give JHL Constructors 5 stars out of 5 stars! It has been an absolute pleasure to work with the JHL team on all aspects of our new building addition. Their customer service, attention to quality and detail, eagerness to go above and beyond to help the building as a whole, and respect for our students and staff has been exemplary. If you are looking for a professional, “go the extra mile” builder, look no further.

Mike Hecker, Lotus School For Excellence

Immediately upon JHL’s selection, it became abundantly clear that they really understand the challenges that face K-12 schools in today’s world better than any contractor out there. JHL worked with us from day one as a fully integrated partner with Edison Schools and the design team, and was able to truly stretch our budget to get us the maximum amount of square footage and all of the scope that we desired.

Pat Bershinksy, Edison School District

On behalf of Douglas County School District and the Board of Education, we would like to thank you for the outstanding work you have done to provide state-of-the-art learning environments for Douglas County students over the years. The District is very fortunate and proud to work with the exceptional people at JHL Constructors.

Douglas County School District

Lewis Himes Associates

JHL has great core values and is dedicated to building quality projects. JHL was proactive, professional, and conscientious of our needs and expectations as an owner. They brought forward value based alternatives for our consideration that made this school the best it could be.

Aurora Public Schools

Our Culture & People Set Us Apart.

In 1987, founder John Hachmeister set out to create a different type of construction company. He envisioned a family-like, supportive environment; an employee owned company where hard workers were rewarded, and people wanted to stay until retirement. Over 30 years later, that vision is very much present and a reality! We take exceptional care of our people and their families, so they in turn, they take exceptional care of our clients. At JHL, we celebrate successes together, support everyone at every level, and spend time together outside the office. Every contractor can build buildings, but they can’t give you the experience and people that JHL can. We work hard, take pride in our projects, and have fun!

Team Members are empowered and obligated to adhere to JHL’s Safety Program and immediately report any newly identified hazards, incidents, or accidents. This strong foundation strengthens JHL’s Culture of Safety. Our approach requires a genuine commitment to Doing The Right Thing – Always. Our exceptional five-year Experience Modification Rate illustrates our success. Our Team’s proven track record has received recognition including the Platinum Level National Safety Training and Evaluation Process Award from the Associated Builders and Contractors and we are a Blue Level Partner in OSHA’s CHASE Program. More importantly, our commitment allows for every JHL individual to remain safe so they can return home at the end of each day.
