The Family Spirit!

As a family of z/OS System Professionals, our goal is to educate and assist companies toward the goal of maximizing the return on their investment in z/OS technologies.


How we started?
ESS was formed back in 1995 by several senior systems programmers whose intent was to collaboratively explore the challenges that working with world class companies could provide. 

How we've grown?
At first, this centered around education and consulting engagements, but soon evolved into development efforts that brought us even closer to industry leading companies.  As these relationships were being built and strengthened, ESS attracted technical resources from across North America.  ESS now has a team comprised of technical specialists, programmers, and educators that allow us to work in any z/OS-related industry technology. 

How we've stayed in the game?
Over the years ESS has maintained our technical edge by owning and operating OS/390 and z/OS operating systems using hardware spanning the P390, MP3000, and z9 processor generations. 

Throughout this evolution, ESS has provided a steady hand to organizations around the world.
