About Erkin Systems
15 years of keeping Orange County businesses running — and growing.
Born and Raised in Orange County
Erkin Systems was founded in Irvine in 2009 by a team of IT professionals who were tired of seeing local businesses get burned by unreliable, impersonal IT vendors. We set out to build something different: a managed service provider that feels less like a vendor and more like a business partner.
Over the past 15 years, we've grown to serve over 200 businesses across Orange County — from dental offices in Anaheim to law firms in Costa Mesa, manufacturing companies in Santa Ana, and tech startups in Irvine. But we've never lost sight of what made us different: local people, honest pricing, and genuine care for our clients' success.
We believe small and medium businesses deserve enterprise-quality IT without the enterprise price tag. That's still our mission today.
Our Values
Honesty First
We tell you what you need — not what's most profitable for us. No upsells, no jargon, no surprises on your bill.
Speed Matters
Downtime costs money. We respond fast, resolve faster, and document everything so the same problem never happens twice.
Community Roots
We live and work in Orange County. Supporting local businesses isn't just business to us — it's personal.
Continuous Improvement
Technology changes fast. Our team holds active certifications and trains continuously to stay ahead for your benefit.
