In 1985, John Haller and his wife Megan created Mainframe Environment.
Unlike other companies, the upper management of our company has never changed.
John and Megan continue to manage Mainframe Environment, providing the best service for maintaining computer environments.
We're only as good as our employees.
Our service crew defines all our years of success. Most of our employees have been with the company for over a decade, demonstrating an unparalleled level of commitment and dedication to our quality of service.
Our employees love working for Mainframe - and it shows!
