An Entrepreneurial Drive
Driven by an entrepreneurial spirit and a desire to create new opportunities for his family, Dean Minardi pursued an opportunity to relocate his young family from Southern Wisconsin to Duluth in the early 1990s. Over the past three decades, Dean has instilled that same spirit in his sons, Nick and Mitch, who now lead the companies with the same integrity, vision, and passion that first brought their family to the area. From this legacy, The Minardi Companies were born. Today, with investments spanning HVAC and Mechanical Contracting, Building Material Supply, Construction Management Services, and Manufacturing, the Minardi family remains committed to making meaningful contributions to these industries and to the community they call home.
