A&A Fire Protection was founded in 2005 by Jose Francisco Mosco SR., Francisco (Frank) Mosco and in loving memory of Angie Mosco. In the last three-quarters of a century a lot has changed – technology, governments, world economies, the materials we use in our daily lives. But, one things remains unchanged – our dedication to doing the best work in the California, Central America, and South America region. We keep an old fashioned attitude about work, and that's that it needs to be done when we promised. More and more, that means relying on brilliant engineers and hardworking skill technicians and craftsman working in tandem.
