The Best Compliment Is The Referral Of A Customer

“I don’t normally write reviews of companies I do business with, but Greiner Buildings, Inc. (GBI) is an exception. I contracted with GBI to construct a large pole barn in January 2018. The experience has been nothing but positive. Joe & Zach M. are super easy to work with and super responsive. Joe handles the initial consulting, design and sale while Zach supervises the field operations. I can’t say enough about Zach – he handles his crew professionally, always shows up when he says he will and works during the crappiest weather you can imagine. I would highly recommend GBI, Joe, and Zach to anyone interested in building a pole barn. I’m kind of cheap, but writing the checks throughout the construction phase didn’t bother me a bit because they earn it.” James C.
