Outstanding experience. I had previously received an estimate of ~$4K to replace the phone system in our office because the staff was having difficulty hearing clients clearly. On a recommendation, I called Greenhill Communications for a second estimate. Joe from Greenhill (owner) was very friendly, professional, and knows his stuff. Even more impressive was his integrity. He stopped by within 2 days and after looking at our phone system (which is only 8 years old) he suggested that we start by replacing a few of the phones that were problematic, not the entire system (phones, control board, etc). Phones were ordered, installed and are working like a charm. Saved well over $3,000. I highly recommend Greenhill Communications. You won't get ripped off. read more
