In 2017, Greenheck Group, a Wisconsin-based manufacturer of air movement, control and conditioning equipment, announced plans to open a new campus in Tulsa, Okla. The first phase of the company’s expansion to Oklahoma included a $100 million capital investment and construction of more than 200,000 square feet of operational space and 20,000 square feet of office space. Since then, Greenheck Group has added significant square footage, growing their presence in Tulsa.
