To Whom It May Concern

 

Joseph Dereef and his quality staff have been working for us since 2001, In the summer of 2001 we were a small hosting company with only few servers. Since then we have grown to have data centers across all of western Florida and the rest of the east coast. J Dereef Contracting Group was able to help us grow our hosting company into what it is today. Josephs knowledge of voice and data communications is unmatched. We will be using them well into the future of our company – Billy Redmond – Zellh0st Technologies

We recently relocated from Powder Springs to our new corporate office in Atlanta. We had heard nothing but good things about J Dereef contracting group around the industry and wanted to make sure the job was done right. Joseph was able to lay out a cost effective solution for us with his bid. He was able to drop the phone lines and network cables in only 3 days, quite a feat for our 12,000 SQ foot office. You can tell when you first meet him and he goes over the plans with you that he takes his job very seriously. Kudos guys  - Catherine ValdezPhone Wiring install atlanta

We had been researching ways to reduce our monthly bills and decided that converting our 200 phone lines from copper to VoIP would be a good place to start. We took many bids from many network cable contractors and J Dereef contracting group was by far the most reasonable. His staff was pleasant as they rewired our entire office for our new telephone system they even plugged in the phones for us. We are now savings thousands per month just by investing a little money and time in Joseph and his staff – Renee Farnsworth Credit Counseling of Maryland-

It was only a few days before we were moving into our new office, The landlord failed to tell us that the office didn’t have active high speed network points. In panic I quickly started calling around. I was able to talk to Joseph who quickly assured me he could meet our deadline. Low and behold J Dereef contracting group saved the day. They showed up to my new office and punched out 10 access points and dropped phone cables as well. Thanks again for everything guys Andy Schomen  Trenton NJ – office-relaocation-cabling
