SAI is a family business founded in 1985 by William Stiefel Sr., and was originally based in the Kalamazoo, Michigan area. Within the next 10 years he was joined by his four children as the business continued to grow.  Our success is due in part to partnering with some of the best quality and customer-service driven manufacturers in our industry. These products are used in every type of food service operation including K-12 schools, universities, hospitals, long term care, chain restaurants, stadiums, fine dining restaurants, convenience stores and vending operations.
