We have worked with National Telesystems for several years. During our recent move, they provided us with great service, recognized and accommodated us when work became urgent and met our needs all the through the process. Working with this team was a pleasure and I would highly recommend National Telesystems for your telephone and cabling needs.

Excellent partnership where the COO walked the project in advance to assure they would meet our schedule. Great planning and execution by the onsite team. Flexible, customer centric and responsive to identified problems. I highly recommend them.

My Company replaced a 10+ year-old phone system with a new one through National Telesystems Inc and the whole process was awesome from the point-of-sale, project management, installation and add-on services. The actual switchover was seamless from the old to the new systems with absolutely no interruption to our workflow and it was a hassle-free process that made me breathe easier as the accountable manager of the project and for the entire Company. I enthusiatically recommend National Telesystems Inc.
