In 1981 Robert’s son, Chris J. Grau, a graduate of Luther College with a Business and Biology degree joined the business to carry on the tradition that Robert had begun. Chris works to maintain relationships created by Robert B. Grau while also establishing new relationships to maintain the tradition of proper woodland management. Chris would also go on to modernize the sawmill and equipment to improve production and success of the business. Chris sees the importance of running an appropriately sized sawmill for the area’s timber resource.
