About Us

Supreme Structures is a general contractor and design-build construction company working in the Madison, WI area. We have built a reputation as a quality and integrity based general contractor in the commercial sector.

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.

Supreme Structures emphasizes service after the sale, centering all business practices on maintaining lasting business partnerships. The business concept has resulted in much repeat business, “one phone call” emergency repair, and regular maintenance for our clients.


“Supreme Structures, Inc. is dedicated to effectively and creatively accomplishing the construction and design-build needs of our partners. We work to understand our clients’ values and business goals to tailor the process to their unique business. Our team treats our clients’ investments as our own before, during, and after construction.”

We strive to cater the build process to the needs of our clients, providing “Solid. Solutions.” to any obstacles that may arise.
