Our Owners
*Brandon Hager*
Brandon has been around construction all of his life, with his father, grandfather, and several uncles being in the commercial construction industry. He started working in construction during the summers at age 16 and 17, and after graduating from Dunwoody College of Technology in 2002, he went to work for one of the larger drywall companies in the Twin Cities area. He quickly caught onto the estimating and project management side of things, working on larger projects over time. He has gone through all of the cycles of this construction industry, learning a lot and building relationships along the way. Outside of work, Brandon lives in Forest Lake, MN with his wife and 3 boys. He enjoys all of the outdoor activities including fishing, recreational boating, snowmobiling in the winter, and many others.
*Jack Mulcahy*
Jack started work in the commercial drywall and plaster industry in 1994, starting out at the age of 17. As the son of a millwright, his interest in construction was cultivated by the many hours spent in the garage with his father, learning to weld, use various tools and equipment, and learning to cuss about old cars, rusty bolts, and the skinned knuckles that go along with it. While attending school at the University of MN, Jack continued working summers as a plasterer, tender, laborer on demolition crews, and as a carpenter. By 2011, Jack and his new business partner, Brandon Hager, launched Pinnacle Wall Systems, bringing with them their knowledge, advice, good and bad experience, and passion for success.
