Pretty basic in terms of projects, but not knowing a damn thing about AV, AND given the wiring in this place is from 2008 with cables behind the walls, he went over what was going on, provided some options, and took care of biz seamlessly. He even took some time to walk me through the details of updating the speaker system that runs through the whole house (the "zone" stuff). A real charming gent, super thorough and detailed, with great comms. Thanks my man! If we do that swap over to the Sonos system (or any other AV stuff), we'll be calling.

Apparently there were some infrastructure issues that had to be addressed first. Upon receiving high estimates from multiple companies, we were referred to Sierra by one of our newest clients. Mike came out to assess and provided simple and effective solutions. He was able to redesign our entire network, install brand new equipment with the required security levels and all at a fraction of the cost we had initially anticipated. His knowledge, attention to detail and abundant patience with us was truly appreciated. Thank you, Mike.
