Bill, much like his father, began working at Reiner Group as a young man working in the sheet metal shop. He spent many summers sweeping the warehouse and learning how to install air conditioning and heating as an apprentice. Once old enough, he was operating as a lead residential mechanic. However, he too went to Calvin College to study mechanical engineering and graduated in 2008. Upon graduating, he came back to Reiner Group to work in the commercial department. Since 2008, he has earned his P.E. and now manages the entire commercial department for Reiner Group.
