Dataflow Networks

An Industry Leader Since 1999

    In 1999, Mike and Heather Johnson realized there was a need in the local area for IT outsourcing for small to medium-sized businesses. They collaborated on some ideas for how they could provide a better service to fulfill these companies needs to maintain their networks, while at the same time reducing their overhead. An industry leader was born. Dataflow Networks hatched from it's nest with the initial signing of the business license. But a license to do business is not a guarantee of worth. Mike's steady hand and continuous research practices, along with Heather's diligent financial guidance, and the support of their talented associates, have made Dataflow Networks a top competitor in the field of local I.T. out-sourcing in the East Bay.
