What we do
One team that knows you by name
From a quick question to your whole network, you get the same people every time — never a call center, never a stranger reading your file for the first time.
Concierge IT
A direct line to people who already know your setup. Proactive care and fast answers — never a ticket queue or a stranger.
3CX VoIP & PBX
Platinum 3CX partner. Licenses, hosted PBX, and expert support for your phone system.
AI Solutions
Chatbots, custom AI agents and MCP integrations — practical AI that does real work, wherever your business runs.
pfSense & Network Security
Netgate pfSense firewalls, VPNs and multi-WAN — a properly defended network edge, not a consumer router.
Cybersecurity
Endpoint protection, email security, awareness training and monitoring — the layers that live beyond the firewall.
Risk & Cloud Services Audits
An independent look at your cloud, accounts and exposure — what you have, what is at risk, and how to fix it.
HIPAA Compliance Audits
Structured HIPAA assessments for practices and their partners — gaps documented, remediated and review-ready.
Cloud & Microsoft 365
Microsoft 365, Google Workspace and everything between — licenses plus expert setup and support.
Websites & Web Apps
WordPress and non-WordPress sites — hosting, management and security — plus custom web applications we build.
