Proactive IT planning

Whether an organization is large or small, the act of planning is critical. Planning starts with understanding the business and the current state of IT. It culminates in the implementation of wise technology that is well suited to the business needs.

Help when you need it

We have a large remote IT Response Services team, but 80% of all requests are handled by the same, dedicated person. That lets us personalize support and ensure that your team knows the name and face behind each support request. We are driven to keep response times blazingly fast and ensure issues are taken care of as quickly and professionally as possible.


It’s impossible to deliver effective and secure IT services without a deep, disciplined approach to security. 100% of Mainstay clients receive a tested security model as part of our service delivery, with the depth of expertise to scale with the organization.

Cloud services

We are a Microsoft Cloud Solution Provider – just one example of our commitment to leading our clients to the cloud wherever it makes sense. We have migrated thousands of email accounts to Office 365, we backup hundreds of local servers to the cloud, and have numerous clients with all servers hosted in the cloud.

An intentional IT department

We provide the power of a results-oriented enterprise IT department to small businesses. There’s a lot involved in doing that – from how we procure over $1m of equipment for clients each year, to how we monitor system health,  develop Disaster Recovery Plans,  report on IT and ensure 100% of systems get fully patched.

A personal team

With all the things we do, the feedback we hear from clients the most is “I love working with ___!” It’s true – what sets us apart is our team of credentialed, passionate professionals. Our clients works with a small, dedicated team, while leveraging all resources when necessary. We love what we do and it’s the success of our clients that motivates us each day.


Before trusting anyone with such a critical component of your business as IT, we believe it is important to ensure you have similar values. Mainstay’s mission and values focus on our impact on people, the integrity with which we walk, and an intentional approach to harnessing the latest technology.
