Welcome to CORE Utilities

Information Technology is critical to the success of any business and CORE Utilities has been a trusted IT service provider to our client partners throughout Sonoma and Marin counties since 1997. Outsourcing IT to CORE is like having an in house IT staff without the administrative costs and hassles. Our job is to keep your network secure, reliable and running at peak performance!

Our Mission

Our mission is to deliver the vital technical support and powerful Information Technology solutions our clients need so they can focus on their CORE business and not on IT problems.

  • About CORE

    CORE specializes in helping "businesses" get the most out of their IT systems by providing managed services, end-user support and technology consulting all tailored to our clients specific needs.

  • Time Management

    CORE takes time management to the next level for our clients by proactively managing IT infrastructure, maximizing networks speed, performance and stability of systems. We work to prevent any problems before they can cause interruption in your business operations, resulting in downtime and financial loss.

  • Your IT Department

    Most businesses need help with their information technology systems but many small to mid-sized companies cannot afford the operational hassles of having a full time IT staff. With CORE you gain access to a team of IT professionals with knowledge and experience in the rapidly changing IT industry.

  • Need IT Solutions

    CORE adds value to our client partnerships by helping them make intelligent business technology decisions. CORE never tries to sell specific hardware, software or technology solutions. Instead CORE focusses on helping business meet their goals.


The North Marin Water District employed CORE Utilities to manage its IT network in July 2008. The District has about 70 PCs, 5 servers and one remote location. Prior to CORE the District employed in-house technical support, but suffered chronic downtime and network problems. We added an outside consultant, which increased IT cost but only marginally improved network reliability. Finally we brought in CORE Utilities. CORE spent significant time during their first months revising server settings, replacing faulty wiring, and correcting router installations. The District's network now runs smoothly and computer-related complaints have virtually ceased. I highly recommend CORE Utilities."
