IT that keeps a practice running, and the marketing that fills it
We start with the technology your day depends on, then help with the website and search visibility that bring the next customer or patient through the door.
Managed IT support
Help desk, device setup, user accounts, security basics and backups for your team, on-site or remote, under a monthly retainer you can plan around.
Healthcare IT and EMR
EMR administration, data imports, reporting and user support for clinics and occupational health programs, with workflows that boost your operational efficiencies.
Microsoft 365 and business email
New setups, migrations from GoDaddy and other hosts, license clean-up, shared mailboxes, and clean offboarding when someone leaves.
Networks and Wi-Fi
Office networks, Wi-Fi that covers the whole suite, firewalls, and cabling that's labeled so the next person can understand it.
Business phones (VoIP)
Cloud phone systems, call routing, fax, and number porting for small offices and clinics.
Workflow automation
Intake, scheduling, forms, reminders and reporting connected together using tools you already pay for, so fewer things depend on someone remembering.
Websites, SEO and AEO
Technical SEO, local search, and answer engine optimization, plus the DNS, redirects and CRM work that keeps a website move from costing you traffic.
Local means someone can actually come by
We're based in Rancho Santa Margarita, so on-site visits across Orange County start from nearby, not from a dispatch center in another county. You'll deal with the same person each time.
Most day-to-day work happens remotely and quickly. When a printer, switch, phone or workstation needs hands on it, we come to you.
Not local? You're still covered. We use remote monitoring and management (RMM) software to watch, update and fix your computers from here, so businesses outside Orange County get the same service as the ones down the street.

We can work with you in two ways: as your managed service provider (MSP), or on a project basis. MSP pricing is a monthly fee based on the number of users and devices and the complexity of your platforms. Projects are quoted as a fixed fee against a written scope. Email us a short description of what you need and we'll reply with a plain-English quote or the questions we need answered to give you one.
