Hi-Tech is Now Part of Centaris
You're in the right place.
In May 2025, Hi-Tech System Service joined Centaris, bringing nearly four decades of trusted Michigan IT service together with one of the region's most established managed IT and cybersecurity providers. Your service continues. Your team is here. And the resources behind it just got bigger.
Two Michigan IT companies, one stronger team.
Hi-Tech System Service was founded in Casco, Michigan, in 1987 and spent 38 years building a reputation for dependable IT support across businesses, schools, and municipalities throughout the region. In May 2025, Hi-Tech joined Centaris, a Sterling Heights-based managed IT and business technology firm, bringing both teams under one roof.
The full Hi-Tech team came along, meaning the same people who knew your systems, network, and priorities are still supporting your account. What's changed is the depth of resources behind them: a larger engineering bench, a 24/7 service desk, a dedicated cybersecurity practice, deep Microsoft expertise, and the compliance experience that comes with serving regulated industries day in and day out.
Hi-Tech has built an impressive legacy of service and client trust. Together, we'll broaden our reach, deepen our impact, and continue delivering innovative, dependable solutions to the communities we serve.
— Patrick Casey, President & CEO, Centaris
For municipalities, schools, and other public-sector clients in particular, the goal is simple: continuity of service first, expanded capability second. Nothing about your day-to-day support has to change. Everything about what's available behind it has improved.

Frequently Asked Questions
Common questions from Hi-Tech clients and municipalities.
Is my service contract with Hi-Tech still valid?
Yes. All active Hi-Tech service agreements transferred to Centaris as part of the acquisition and remain in effect under their original terms. You don't need to sign a new contract for service to continue. When your current term ends, your Centaris account manager will work with you on renewal options.
Will my pricing change?
Existing pricing under your current Hi-Tech agreement is honored through the remainder of your contract term.
Who do I call for support? Is the old Hi-Tech number still working?
Use the Centaris support contacts listed in the support section above.
Are the same Hi-Tech engineers still supporting our account?
Yes. The full Hi-Tech team joined Centaris, including the engineers and support staff who have been working with your environment. They now have a larger team, a 24/7 service desk, and additional specialty resources behind them — but the people who know your systems are the same.
How do I log in to the client portal?
Click the Service Support icon in your system tray, provide some basic information, and a ticket will be created for you. If your previous Hi-Tech login isn't recognized, contact your account manager or email support to have it reset.
We're putting together an RFP — how should we list the vendor?
Centaris is the legal entity that now holds the Hi-Tech service relationship. For procurement and bid documents, the vendor name is Centaris. For W-9s, certificates of insurance, or other vendor-onboarding paperwork, contact
Do you still serve municipalities specifically?
Yes. Public-sector clients — including municipalities, school districts, and other local-government bodies — continue to be supported. The acquisition expanded capacity in this area rather than reducing it.
How do I get in touch about a new project or expanded services?
Reach out to your existing account manager — they're still your primary point of contact and can pull in additional Centaris resources as needed. If you don't have an account manager assigned yet, email [email protected] or call 248-284-7171.
Still have questions?
We'd rather hear from you directly than leave anything ambiguous, especially for clients with active contracts or municipalities preparing procurement documentation.
