Values & Culture

Reputations for quality and excellence don’t come easy in Chicago; they’re earned from years of proving you can deliver results. It takes commitment, know-how, and lots of hard work.

Our values guide everything we do and express what’s important to our family and our team members.

Human Qualities

When asked what makes Great Lakes so successful, George J. Treutelaar said it best back in 1978 (and it still rings true today) …

“What makes our company so successful? I think I know the answer. First and foremost, it is the pride the company takes in the quality of its work. Secondly, I think it is the confidence we feel in the ability and high professional standards of our fellow workers. Third, I think we have been fortunate to have had outstanding clients who have provided us with remarkable opportunities and challenges. And finally, I think it has been the human qualities that have made our company what it is because I have seen these qualities reflected in every aspect of our business. Pride in our work … respect for professionalism and high standards … the desire for challenge … the creativity to innovate.”

INTEGRITY

We speak honestly. We treat everyone with respect. We communicate with purpose. In other words, we do the right thing. Period.
