When our team and our philosophy work together, the result is successful and satisfied clients. Here’s what some of them have to say about ATSI:


“I’ve done business with ATSI for a number of years now. They are as professional and honest as it gets. They come highly recommended for telephone systems and structured wiring. Their solutions are second to none and they are a joy to work with.”

“ATSI has been handling our phone equipment for over 10 years. We recently transitioned to a cloud-based phone system with seamless efficiency and no hiccups, thanks to the team at ATSI. All of their technicians and managers are super helpful and take the time to explain everything. They also helped us with the appropriate selection of equipment and headsets that best suit our needs. We would gladly recommend them to anyone.”

“We have been customers of ATSI for around 20 years and have had nothing but good experiences with them. We recently installed a new phone system and ATSI helped us from start to finish and is still helping us make little tweaks as needed. I can’t say enough good things about this company. Make them your phone provider — you won’t be sorry!”

“ATSI has been New Century Financial’s valued vendor for all our telecommunication needs for over 13 years! They had helped us through 4 office relocations and now that we’re settled here in The Woodlands, they continue to provide personalized customer care and professional service. I can always count on their team to take care of regular or high-priority and last-minute service requests. I highly recommend ATSI for any business telecommunication needs!!! More power to you Tim Martin!!”

– Quennie Zerna New Century Financial

“I can’t say enough amazing things about ATSI! They’ve been taking care of our office phone system for more than 15 years and never had any issues with the phone system, with their work or with their price. We recently relocated and Tim met me at the new location so he could give me a quote on transferring our phone system and while we were there I mentioned that we needed new cabling throughout the office and Tim said he could get me a quote by the end of the day. He got me the quote that same day and their price beat all the other quotes I got from other well known cabling companies. Tim and his team went above and beyond to get the cabling installed and our phone system transferred in a very timely matter. Zane was at our new location on our staff’s first working day to make sure everything was running smoothly. He took care of last minute changes and upgrades. Tim also came by our office to make sure everything went well. ATSI is a company you can trust. We are definitely lifetime loyal customers! Thank you so much ATSI!”
