Who we serve in Tustin
The Tustin business picture
Tustin is really two business cities in one. Tustin Legacy — the redevelopment of the former Marine Corps Air Station, still marked by its enormous blimp hangars — has filled with new retail at The District, modern offices, and growing companies. A few miles away, Old Town Tustin's historic storefronts hold independent restaurants and shops, and the Tustin Auto Center lines the I-5 with dealerships and automotive services. That split defines the IT work here: brand-new space that needs building out on one side, and established businesses on aging systems that need careful modernization on the other.
We cover the full spread — Tustin Legacy and The District, Old Town Tustin's storefronts, the Auto Center along the I-5, and the office corridors between them.
Full-service IT & AI, close to home
Everything we provide for Tustin businesses.
Managed IT Services
Proactive 24/7 monitoring, patching, and management of your whole network — so problems get caught and fixed before they slow your team down.
IT Support & Help Desk
Fast on-site and remote help desk. One call reaches a real technician who already knows your systems — no offshore script-readers.
Cybersecurity
Firewalls, endpoint protection, email security, and staff training that keep your business out of the breach headlines.
Cloud & Microsoft 365
Migration, setup, and day-to-day management for Microsoft 365, Google Workspace, and cloud infrastructure.
Backup & Disaster Recovery
Automated, tested backups and recovery plans so ransomware or a dead server never means lost data or lost days.
Networks & Wi-Fi
Business-grade wired and wireless networks designed, installed, and secured to keep up with how you actually work.
VoIP & Business Phones
Modern cloud phone systems with smart call routing, voicemail-to-email, and mobile apps for your whole team.
AI Automation
AI receptionists, chatbots, and workflow automation that answer calls, capture leads, and cut busywork — the AI edge most IT shops don't offer.
IT Consulting & vCIO
Technology strategy, budgeting, and compliance guidance from a partner who thinks like your CIO — without the full-time salary.
Software & App Development
Custom software, web apps, and phone apps built for how your business actually works — designed, developed, and maintained by the same local team that runs your IT.
Why Tustin businesses choose a local IT partner
CallMOR helps Tustin companies modernize — cloud migrations, stronger security, better phones and networks, and AI automation — with the responsiveness of a local partner rather than a faceless national provider.
Whether it's standing up clean infrastructure in new Legacy-area space or migrating a long-established Old Town business off aging servers without losing a day of trade, CallMOR handles both ends of Tustin's modernization curve. We're about eighteen minutes down the 5 — close enough that 'local partner' means someone who actually shows up.
We also do what most IT shops don't — build AI automation like AI receptionists, chatbots, and workflow tools that cut busywork and answer more calls. CallMOR has served Orange County since 2012: it's managed IT and a genuine efficiency edge from one local team.
