IT you trust from a team you enjoy

Every organization deserves IT that is wisely led, reliable, and secure. Delivered by a team they love working with!

IT complexity is growing. This creates challenges.

Your systems and support model must evolve to keep pace.  If it doesn’t, you may find:

Your team is frustrated

You are concerned about IT

Your organization is at risk

The right IT inspires trust and brings clarity.

This is why Mainstay exists. We are large enough to ensure IT is sophisticated while being intentional to tailor that service through dedicated core teams you’ll love to work with.

How It Works

Contact us and explore a potential fit.

We typically work with 15-500 employee organizations who are in northern New England or are fully remote. If you call, and we aren’t the right fit, we will still provide guidance for your search.

When there is strong alignment, we work together on an onboarding date.

Our Client Transformation team makes the onboarding experience incredibly smooth. We have experience cleanly transitioning from every type and condition of IT!

Your entire organization starts feeling the impact of trustworthy IT on day one.

What our clients are saying

Annalee Dolls, Inc.

Mainstay Technologies is instrumental in keeping our company running smoothly. Their level of professionalism can’t be beat.

Jason Ray, Director of Sales

Nathan Wechsler & Company

The unique quality Mainstay brings to the table is a holistic approach…by focusing on the business goals of their clients. As a business, like ours, that virtually runs paperless, their role as a service provider to our business is a key ingredient to our success, and because of that, I am constantly recommending their services to my clients!

Rusty Mosca, Managing Partner

Belknap County

Thanks to Mainstay, our IT system is more efficient and reliable than it ever has been, and that translates to lower costs and lower stress.

Debra Shackett, County Administrator

Mid-State Health Center

We can’t afford to have a full IT staff with multiple specialists, but we really needed a broader base and a bigger resource. Mainstay was a really good, cost-effective answer for us!

Sharon Beaty, CEO

Granite State Glass

Mainstay has continually exceeded our expectations with their services. They have a very knowledgeable staff and aren’t learning on our nickel, like other companies we have had in the past. I cannot say enough good things about Mainstay, and I wholeheartedly recommend them.

Jon Covell, Vice President
