Z-TECH is a proud sponsor of organizations in the greater Boston community including the Bike Connector of Lowell, the Carroll School, Boys and Girls' Club, Salem Academy Charter School, and Theatre III of Acton.

Based in the Boston area but servicing clients across the US and globally, our team of experienced engineers, technical account managers, project managers and support staff have spent the last two decades helping clients envision, implement and support IT infrastructure. 

Zeus Estrada founded Z-TECH Associates in 1989 while working in the academic community on VAX projects. As a senior analyst at Brandeis and MIT, he provided integration services to various departments on campus. This experience laid the foundation for implementing some of the first LANs and WANs for private sector companies in the Boston area. 

As Microsoft gained prominence in networking and server operating systems, Z-TECH became one of the first certified partners. Today, Z-TECH is a Microsoft-certified cloud solution provider and assists clients to successfully integrate cloud solutions into their existing sites in addition to supporting all aspects of an organization's IT needs. 

Z-TECH has some of the best systems engineers in the Boston area and beyond. Our comprehensive experience with technology and hands-on approach to installing and maintaining systems for our clients has won us a loyal base of customers.

"Labor day weekend one of the remote servers crashed and a phone call to the site would not fix the problem. Fortunately, we had contracted with Z-TECH, who was able to send their technicians out on one of the busiest weekends of the summer and resolve the problem."
