People Love Our Work!

  • Dorothy B.
    As a published author, I rely on technology for research, interviews, and communication in general. A recent move required a major change in my computer and phone service. Mark and his staff were the first people I contacted because they had successfully resolved some past tech issues I experienced. His team is competent, courteous, and reliable, as well as being mindful that I am a small business with a limited budget. They are excellent problem solvers who understand how customer service should work. I am more than happy to recommend them.

    Our company thought we had a small wiring job to install new phones, but we were wrong. It would have cost us thousands of dollars in wiring. Instead, two very courteous and professional techs had to come out over 4 long days to completely rewire, go into the ceiling, connect from outside of the building. It was a lot of work. They went above and beyond the call of duty and didn't charge us a penny for any of it. EXCELLENT CUSTOMER SERVICE!! Beschelle Lockhart
