It’s the reason we enjoy a long-standing history of developing creative solutions for the most challenging of projects, schedules, and budgets.

We are committed to offering the personalized service of a small firm with all the capabilities, quality assurances, and cost-effective solutions of a large national chain. After all, it’s our plan to keep true to being Integrity Built.


Doug and Tammy Loeffler started the firm in their home basement during the 2010 recession. Shortly after establishing the company in April 2010, they started adding staff.

In January of 2011, against incredible odds, Loeffler secured a large data center project and secured renovation work at the University of Minnesota that provided a healthy backlog and the start of growth and profitability that continues to this day.

Since its founding, Loeffler is proud to have won the following prestigious awards:

  • 2013, the Stellar Award for the Small Business Supplier of the Year from University of Minnesota for its efforts in diversity and inclusion
  • 2015, the O.P.S. Award from the Minnesota Subcontractors Association
  • 2016, the Small Project of the Year Award from the Construction Partnering Program for its Anishinabe Bii Gii Wiin project in Minneapolis
  • 2017, the MCA Project of the Year, “New Project Under $15 Million” for its work on the Tashjian Bee Discovery and Pollinator Center at the University’s Landscape Arboretum
  • 2018, the General Contractor of the Year Award from the University of Minnesota’s Office for Business & Community Economic Development
  • 2019, Ben Nordquist was named Construction Professional of the Year by the Minnesota Subcontractors Association

Client Testimonial

"Loeffler Construction is working with us on a historic property. At the start of the project, they went above and beyond to learn about the property and to understand it's construction. They ensured we had all the mock-ups needed for final SHPO approval of the project."
