Company | Navitas System Integration

We develop customized system integration solutions to reduce building energy use and operational costs.



Navitas System Integration (NSI) in Plymouth, Massachusetts, was founded by president and founder Dan White in 2008. Dan recognized a need among contractors and building owners for comprehensive system-integration capabilities paired with responsive, accountable service.

As an independent company with large-scale capability, NSI offers the best of both worlds. First, we are a certified Siemens Solution Partner including all Siemens Critical Environment (Lab) solutions as well as a Honeywell authorized Building Control Specialist (BCS). We install state-of-the-art systems and develop solutions for major clients with complex project requirements.

Second, we offer the accountability and flexibility of a local company unbeholden to a parent corporation. Our minimal overhead allows us to pass savings along to our clients. We adjust nimbly to project changes and communicate regularly about milestones and progress. Most of all, our co-owners Dan White and Matt Slattery are personally accountable and stand by their word.
