                     LEE RENFROE
My name is Lee Renfroe and I live in Fitzgerald, GA. I have been in telecom/ low voltage for 25 years. I always liked working with my hands and worked at a
car audio shop while in high school. So, it was a natural transition to telecom work. My passion is, and will always be phones because my first 10 years were primarily telecommunications.
I have since gravitated to fiber optics and security because the technology is so cool!
        I worked for BellSouth/AT&T for 10 years, then, I went back to my alma mater, Wiregrass Georgia Technical College, as a telecommunications instructor for 5 years. In 2015, I started my low voltage integration company, GoFroe, which I still own and operate today.
Since leaving the technical college, I have maintained my instructor status by teaching fiber optics classes all over the country. I have taught over 50 classes in the past 6 years, as well as run my own business. It’s great to travel around and meet new people in this industry. Some of the most important people in my career have been people I have met through ETA. My hobbies are traveling and spending time with my family. My daughter is fiber optics certified at 13 years old! Super proud of that! One cool thing that I did this year was teaching an Amish woman how to splice fiber. She was a fast learner and seemed to have a real talent for it!
Lee Renfroe is the owner of GoFroe and is an ETA International Certification Administrator via Light Brigade. For more information, please visit
