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 Stellar Award for the Small Business Supplier of the Year – University of Minnesota for our efforts in Diversity, Equity, & Inclusion
  • 2015 T.O.P.S. Award – Minnesota Subcontractors Association

Client Testimonial

"Loeffler has high standards for building and safety which are appreciated.  They do not take short-cuts.  Any alternative materials compared to plan are vetted through the owner first, and then the architect and engineers.  Communication is a strength of the Loeffler team; updates are given weekly to all stakeholders."
