Our Story

Advent Communication Systems was formed in 2000 and incorporated in 2001 as a communications company, installing and supporting business phone systems. As customers' needs grew, so did Advent: the networks their phones ran on, the computers and servers on those networks, the security protecting all of it, and eventually the cameras and door access in their buildings.

Twenty-five years later, Advent is a technology integrator and managed service provider focused on three areas: managed IT and cybersecurity, cloud communications, and building security. The phone systems are still part of it – now in the cloud as well as on-site.

How We Work

Our mission is simple: Leave Your Technology to Us. Partnering with Advent means having a technology advisor by your side, not just another vendor. We take the time to understand your organization, your goals, and the problems in front of you, then recommend technology that fits your business and your budget.

We're big enough to support very large organizations and small enough to truly care: a knowledgeable team serving about 2,000 customers, led by an owner who's still involved day-to-day.

  • Responsive. Calls reach a live person, and new inquiries are answered the same day or within one business day.
  • Accountable. One team for your phones, network, security, and IT, so problems don't bounce between vendors.
  • In it for the long run. Twenty-five years in business, and planning help that looks past today's ticket to what you'll need next.

To us, service means helping customers manage, maintain, and improve their technology – and keeping it working.
