We called CNS regarding options to strengthen and increases the radius of our data in our mostly concrete/steel building.After the professional install, our reach and connectivity improved from 2MB/S to 100MB/S in our deadzone.Very happy with the end result, Dean and Evan were a pleasure to do business with.

I have referred many of our clients to Dean and his team at CNS over the years. They have excellent work ethics and go above and beyond for their customers.

When you run a business and your computer gives you fits, Certified Network Systems is the go-to organization to get it up and running NOW! I have had some troubles now and again with various computers; Dean Bird and his technicians have always sorted it out in a timely, professional and courteous manner.

I highly recommend Dean Bird with Certified Network Systems. He goes out of his way for his customers and their computer needs!

We at Maine Sea Coast Mission have been very pleased with the computer and network support from CNS for over 4 years. Fast and professional support.
