Located in Southeast Portland's historic industrial district in a restored art deco building, Quadrant's 30 plus year story is embodied in its location. Heart, courage, and sweat equity has restored a Portland classic into a showroom and office that integrate the best lifestyle technology in a way you'd want to see in your home or business.

Our company had humble beginnings over 30 years ago when the owner and founder, Gary Nedelisky, began working out of his garage. The values he ascribed to back then have continued to be the foundation for our company: honesty, integrity, hard work, disciplined, and consistent results. Quadrant Systems is committed to delivering exceptional quality in design, engineering, documentation, craftsmanship, installation, and support.

Our staff believes in building relationships with our clients and getting to know your preferences so that we can offer the best technology fit for your lifestyle, your home, your business.
