TESTIMONIALS

Testimonials

Blue Valley Baptist Church is pleased to have an ongoing relationship with Advanced Sound and Communications. We have engaged in projects with them ranging from simple equipment rentals for special events to large-scale design and installations on two of our campuses. Their strengths are many, but near the top of the list is an ability to think creatively to address not only current needs, but also the long-term functionality of the system in your venue for years to come. Our experiences with them in regard to customer service have all been favorable from telephone reception to installers to follow up. They have our confidence and trust.

John Hollan, Blue Valley Baptist Church

ASC is one of the best integrators we have worked with at Builders For Christ. The installation was very clean. Great attention was paid to the smallest detail. It's rare for an integrator to take such ownership of a project.

Chuck Walthall, Walthall & Associates

The City of Grandview has been a customer of Advance Sound for some 23 years at our Municipal Servers Building, and for the last 15 years at our community center.

Advanced Sound & Communication worked closely with us to get us the best system for our money. Brent continues to be great to work with and is our go to guy for anything audio or video.

Kraig Briggs, City of Grandview

We are very happy with our new system. It works just like you said it would. Your team was very courteous and helpful. The training was excellent. We feel confident we will be able to use our system without any problems. Blessings!
