Alton L. Granger started Granger Construction Company in 1959 with his father and two brothers. Under his leadership the company has grown to become one of Michigan's and the country's largest and most respected family-owned construction firms. The company's rise to success, under Alton s leadership, can be attributed to maintaining the highest level of skill, integrity and responsibility while adopting the Golden Rule as the family score value. 

Alton has been involved with every project undertaken by his company during more than 40 years of operation. The Granger Construction Company has done a wide range of construction work around Michigan but is perhaps best known for its work with educational facilities. In 2004 Alton and his wife, Janice were honored for their lead gift to establish Ferris State University s Granger Center for Construction and HVACR, named in their honor. The Granger Construction Company also built Ferris Library for Information, Technology & Education and other buildings. 

He has received numerous company, personal and community awards. These include an honorary doctorate from Ferris State University and Build America Awards/Partnering Awards from Associated General Contractors in six different years. He was honored as Outstanding Philanthropist of the Year for the Capital Area Chamber, Association of Fundraising Professionals, Outstanding Philanthropist for Michigan State University, Distinguished Citizens Award from the Boy Scouts of America - Chief Okemos Council and the Builders Exchange of Lansing - Honorary Member for Lifetime of Service.
