"Complete the project as though you were building for yourself." Walter Keller
Keller, Inc., was founded in 1960 in Kaukauna, Wis., by veteran builder Walter Keller. Originally focused almost exclusively on large-scale agricultural structures, Keller was instrumental in expanding his company's presence into other industries, including retail, financial and healthcare.
Walter oversaw the company's conversion from a family-owned business to an employee-owned enterprise, through an ESOP (Employee-Owned Stock Option) plan in 1986. Though Walter retired as Keller president in 1989, his original values of integrity, honesty and commitment to putting the customer first still inspires today's highly dedicated professional and field staff.
