My brother in law told me about Mark and I am glad he did. Mark knows his stuff. I booked him for a quotation for my Surround Sound System, he came to the house, and informed me what I needed and what I don’t need(to save money) and spent the time to analyze my house and told me what kind of wiring he will be doing. Gave me the quotation over e-mail. I booked the appointment, he came in on time, finished the job and cleaned up after himself. My system rocks. Thanks Mark.
