Doug was INCREDIBLE to work with! He was very timely responding to my emails, did exactly what I asked without having to go back and forth, was very knowledgeable about what he was doing, professional, and completed the job earlier than I expected! I highly recommend Doug and would definitely hire him again! ~Wendy
