Our History


Our CEO, Bryan Gabriel, founded an IT consulting and computer services company in Columbus, Indiana. While running the company, it became apparent to him that there was a massive need for affordable, high-speed internet in Indiana’s rural communities.

He founded a wireless internet service provider and over time, as he researched fiber optic technologies, this wireless internet venture slowly morphed into a fiber optic internet company. This company eventually became the Mainstream Fiber Networks you know today.


Mainstream Fiber Network’s first major build was completed. The project was to ensure that all students in the Brown County Schools had fast and reliable internet. Shortly thereafter, the company began to expand its fiber-optic network in Brown County, providing over 21 miles of fiber-optic cable.


Mainstream Fiber Networks began expanding their coverage into Harrison County before partnering with the Harrison County Community Foundation and the Chamber of Commerce to begin work on an enormous 115 mile fiber optic loop that provided service throughout the county.


Shortly after the partnership with Harrison County was finalized, Mainstream Fiber Networks underwent major growth, doubling in size.  The company has continued to double in size every year since.


The mainline fiber loop in Harrison County was completed. This loop provides over 115 miles of fiber to over 100 neighborhoods and over 8000 homes and businesses throughout Harrison County.

Due to interest in the community, the project’s scope was able to be increased, and an additional 115 miles were constructed, doubling the total size and coverage of the project!  Mainstream intends to keep expanding the network throughout Harrison County through the coming years.


Mainstream Fiber Networks expanding coverage into neighboring Floyd County, and also began to work with Warrick County Economic Development on a milestone fiber optic project.  Mainstream Fiber aims to continue growing, expanding our network and providing affordable internet solutions throughout all of rural Indiana.
