About Us


Supreme Structures, Inc. was established in 1992.  Dan Bertler is sole owner and president. Bertler and the Supreme Structures team work on projects including retail and restaurant, large commercial buildings and showrooms, convenience stores, and tenant build-outs. 

Local convenience stores have been clients of Supreme Structures since the 90s.  This foundation of experience has allowed the team to translate efficiencies and consumer and employee convenience into other industries.

Supreme Structures moved to a new office building in July of 2013.  The newly renovated office is located at 2906 Marketplace Drive in Madison.  Click here for directions.

Currently, Supreme Structures employs 16 full-time employees.  Based on the given project, we hire independent architects, engineers, and consultants to supplement our team.  This business model allows Supreme Structures to build a truly personal construction team.

After receiving the 2012 Dane County Small Business Award, In Business featured Supreme Structures with an interview with Dan Bertler.  The article featured Supreme’s modest beginnings, client-focused business concept and the team’s motivation for putting it in to practice.
