About Primus
Brands We Serve


When Richard O’Connell and Erik Gunderson founded Primus Builders in 2000, their goal was to provide specialized construction services to the cold storage and distribution industries. Since then, Primus has grown to become a leading provider of design-build services for the distribution, food and beverage and medical device sterilization industries. Primus’s team of more than 90 specialists includes site selection experts, architects, engineers, process planners, estimators, thermal construction and construction management professionals all dedicated to providing superior design and construction services on every project.

Primus has grown to include three divisions: Primus Design Services, LLC; Primus Builders, Inc.; and Primus Thermal Division. Each company specializes in a specific component of the design-build process that, together, are the foundation of the firm’s single-source approach. Because all three companies are located under one roof, communication is effortless. Primus is able to implement owner goals into a single agenda that delivers projects within budget, schedule and to the owner’s desired level of quality.

Primus has been the design-builder of choice on over 300 projects. The majority of these are repeat business and reflect the firm’s commitment to building lifelong relationships with its clients.

At the core of Primus’s philosophy is an unyielding dedication to fair and ethical business practices. Primus is committed to doing the right thing in all aspects of business – with owners, vendors. stakeholders and employees. In 2008, Primus furthered its commitment to this practice by appointing Dr. Paul Voss as an advisor and member of the firm’s Board of Directors. Dr. Voss is an expert in ethics and serves as President of Ethikos, a private firm specializing in the exploration and application of ethics in corporate, social and legal environments. His efforts have guided Primus to success based on principled business practices.

Primus has consistently been competitive and able to deliver a quality product for us throughout the U.S. and Canada. From renovations and additions to new construction, Primus is on my call list!”
