My law firm, based in San Francisco, California, retained Dia Systems in early August 2018 as our remote IT service provider. This company has exceeded all my expectations. Dia Systems is very responsive to all of my team's IT support requests and always sees them through to resolution. It is also exceptionally well-managed--something I definitely appreciate as the owner of my own small business. I would give this business ten stars if I could. Highly recommended!
