Johnson Systems Inc.

Due to the rapidly developing COVID-19 Pandemic, Johnson Systems Inc. will remain open but with much reduced operations effective March 16, 2020. We feel we must do our part to stop the spread of this disease by protecting staff and provide them the opportunity to self-isolate with their families at this time.

We are still quoting projects, accepting orders and shipping products just not at the normal quick service speed we have become known for. We ask for your patience and will continue to provide the best service possible. We hope this situation can be overcome quickly and we can return to normal operations.

Stay Safe!
