Our company patriarch, Walter P. Znamirowski, was a proud World War II veteran whose principles helped shape the culture and values of our company. Though he is no longer with us, his belief in hard work, accountability, and service continues to guide how we operate today.
In honor of Walter’s legacy, we remain committed to supporting and employing veterans, and carrying forward the tradition of discipline, craftsmanship, and professionalism that he inspired throughout the organization.
