Where it all started

In 2010, Larry and Claudia Walker faced a decision—continue building someone else’s business or start their own. After many years of experience in the low-voltage security industry, they founded All State Systems Integration (ASSI) to provide quality security and building systems solutions.
Starting with zero staff and zero capital, they grew ASSI into the trusted name that it is in commercial security alarm systems, fire protection, video surveillance, and full building systems integration. Within just three months, they secured partnerships with National Accounts, general contractors, and local businesses, expanding their reach across the greater Sacramento area, Reno, Portland, Seattle, Idaho, and Montana.
