Why AJTC
The IT partner that feels like part of your company.
Big enough to cover every part of your IT, small enough that the person who helps you knows your name and your network.
Meet the team
A team that already knows you
You get a dedicated team that learns your people, systems and quirks. No re-explaining your setup every time you call.
A real person, right away
Every request is acknowledged instantly and picked up by a technician, not left in a queue or bounced between call centers.
Process, not guesswork
Documented standards for onboarding, patching, security and changes, so your IT behaves the same way every day.
Security built in
Endpoint protection, email filtering, backups and user training come standard, not as surprise add-ons.
Over the last four years we have grown from 100 employees in one location to over 600 across multiple locations. AJTC's expertise and guidance allowed us to always be ready for rapid growth. They truly operate as an extension of our business, as if they were our own in-house IT department.
"AJTC was instrumental in bringing our practice into the digital age… their expertise in servicing the medical industry has allowed them to understand the core needs and workflows of our business."
"As a small business we rely on AJTC to do what they are good at so we can do what we are good at."
Mike Carney Flow-Technics"From on-site and remote support to custom software development and database management, AJTC has played a large role in our company's success and growth."
