Fritz Budig - President and CEO
763-777-9557 | fritzb@grindstonecs.com

Fritz started in the construction industry working for his father in his family’s construction business. After serving in the 82nd Airborne division during Desert Storm, he partnered with his father and together they ran a successful residential construction company. After his father’s passing, an opportunity arose for Fritz to transition into the commercial sector. Over the years Fritz has gone from superintendent to managing project managers and superintendents to finally realizing his dream of owning his own commercial construction company.
His father’s guidance coupled with his military background has taught him the value of being a positive leader, having strong work ethics and building lasting relationships. Fritz lives with his wife Stacie and their 2 children in Buffalo, MN. Together, they enjoy fishing, hunting, boating and coaching their children’s various sports teams.
