About Us

Established in 2010. 

GEFNET is a small business in Mattoon, IL 

The business was a decade plus in the making and stemmed from a life long passion for computers/electronics. Whenever something would break or stop working friends and family would come to me to fix their computers and after a few years of doing this the word spread and friends of friends would come calling. It's then i realized that I could make a living doing this. 

After doing side jobs for many years gaining experience from all the jobs I've done I wanted to make the business official but didn't know how so a few more years passed and after building a vision for the business and having everything laid out I made it official in 2010. 

GEFNET has been serving customers for quite a few years now and with hundreds of customers under our belt we are confident that no matter what problem comes up we have been there and done that for the most part. We look forward to growing and learning year after year. 

About The Owner/Lead GeeK: 

Greg Fultz, Born in 1975 born and raised in Illinois. I eventually ended up in Alamogordo, NM where i officially opened the business and then moved it back to the home state. 

I Graduated from New Mexico State University and I have a degree in Information Technology and I'm a certified Network Specialist. 

My Motto is "People Before Profits."
