What began in 1991 as a quest for a better way to train IBM mainframe personnel, has now cumulatively trained over 1 Million mainframers globally, and is now the world’s most awarded, most delivered, most IBM credentialed, IBM Z mainframe training annually.
We are mainframers, and we are proudly part of the global mainframe family! We collaborate closely with IBM and the major mainframe industry vendors to develop the finest training on their products. We train the mainframe workforces of a majority of the world’s mainframe organizations. We give back to the industry, donating our courseware extensively to countless next generation mainframers worldwide.
We understand that as well as you wanting to train and empower your mainframe computing workforce, you also want to do business with friendly, helpful, experienced people!
Know that we are here for you!
