NetworkChuck (Chuck Keith)

I am a Cisco Certified Network and Voice Engineer with a passion for all things technology. I have spent most of my time mastering the world of networking and collaboration but still find myself dabbling in systems and programming. As much as I consider myself an engineer/admin, I mostly assume the role of student in my daily routine, constantly learning a new technology and looking for ways to apply it to my job.

Providing solutions for customers is my favorite part of the job. I come from a sales and customer service background and I think this has been instrumental to my success. Knowing the technology is key but knowing the customer is what sets you apart.

Current Certifications:

-CCNA Routing and Switching

-CCNA Voice

-CompTIA Security +
