To all companies who depend on PCI – Performance Contracting Inc. in Knoxville, Tennessee to do their industrial cleaning, watch out! They will try to overprice. Take your business elsewhere if and when they do this. PCI Operations Manager, Esley Hall and his incompetent protege, Elise Brown are known for ripping off companies and even scamming their own employees out of their hourly pay. Their personal behavior is very shady, and immoral, as well. Google their names and read for yourselves. They’re not professional. Bad for business.
