Too Many Engineering Projects for Your Team to Handle?
We’ve Got Your Back and It’s All About Our Team.
Our Executive and Client Leadership Team:
Karin Williams, President and CEO


I’ve been told I’m a good judge of talent and I’m proud of the team we have built, and the employees and consultants who have been a part of RioTel’s history. Actually when I started RioTel, I just wanted to create a company and reputation for excellence around my expertise, in the telecom industry that I love. I had no idea what a thrill ride we were in for as our clients worked hard to keep up with demand in coverage, capacity, and innovation–fueled by the explosion of the internet, smartphones, tablets and other devices. We have been proud to be with them every step of the way as we are Building Tomorrow’s Networks. It’s really exciting being part of an industry that has such a positive and transforming impact on our daily lives and the world around us.
