What Makes Us Different

At Mainline, we use our technical skills and consultative approach to build solutions for our customers that enable them to tackle their most critical business initiatives.  We believe in positive outcomes, with lasting change, not quick fixes, and not one-size fits all. The team at Mainline supports customers through the entire lifecycle of the solutions we build, implement, and manage for them.


In a world where there are lots of options for your business challenges, Mainline has taken a consultative approach to understand the “why” of what needs to happen instead of just selling a product and getting me a quote. I think their approach is a lot different.

“We have an excellent level of trust in Mainline. They’ve been there for us, helping us through migrations, and equipment and system transitions. When they addressed cloud latency issues, we saw great results within the first week.”

Melvin Pena, Associate Director of Technology, Mount Sinai Health System

“We were able to go to advanced flash storage, an advanced server environment and more capacity, and our annual operating costs actually decreased. This is a testament to everyone involved, including Mike (Karasienski), Chris (Walker), our management team, the IT staff and Mainline. I’ve never seen a migration happen that quickly and smoothly before.”

John Hill, CIO, Carhartt

“Mainline did a great job. I expected the project would take a couple of months, and they knocked it out in 4 weeks. The project leader ran the project flawlessly. I’ve worked with Mainline before and I used them again because no matter what project I have them do, they’re there ‘til the end. They’re a great partner.”

Paul Jones, CTO, Sisters of Charity Health System

“Mainline’s consultative approach and expertise enabled us to select, design, and implement the optimal networking solution for Victor Central Schools. The classroom experience is elevated, and our students and staff couldn’t be more pleased.”

David Henderson, Director of Computer Services, Victor Central School District

We’re really happy with our selection, and we’re always amazed at how well Mainline knows our environment and our needs. In the past 10 years of working with them, they have never been wrong. We trust Mainline.”
