Accountable for Excellence
I appreciate the upfront planning, hard work and dedication of the entire Neumann Brothers team to make the Griffin building project a reality. We knew this project was going to be filled with challenges and obstacles. This is why we put our trust in Neumann to be our General Contractor partner. They paid special attention to the historical construction details and quality we expected. Their open and transparent pricing was key to staying on budget. Today, the Edna Griffin building’s construction and message stand as historical icons and make the entire State of Iowa proud.Tim Rypma
