Built In A Basement

Network Solutions began in 1989 as Larry Tadevich’s solution to the tension of balancing work and family. Driven by a desire to provide for his family and honor God, our foundation is a blend of doing business with excellence and integrity. 

Taking a leap of faith, Larry and his wife Sandy built a thriving business together out of their unfinished basement. Seeing growth, they brought on their son Bill, to handle everything from sales to engineering which only enhanced our reputation for competency and character.

Bursting At The Seams

By the time we hit 1995, our little startup had outgrown the basement and transformed into a full-fledged company with our own office serving businesses around the Midwest.

Through the years technologies have certainly changed but our unwavering commitment to customer success has not.
