Arno led the training session perfectly. With his laid-back style, he presented the information in a very accessible way and addressed all of our questions. The included workbook effectively highlights the most important information. It was fun!

The online training was good, but it would have been much better in person. The training was very informative, and the materials are very well organized for learning. Thank you again!

The training was: - lively and personal - enriched with real-world experience - good preparation for certification (at least that's how it seemed; a final assessment will only be possible after the exam :-) ) - interactive; Arno encouraged participation and addressed questions

Arno was really patient and used real-life examples to help us understand the abstract ITIL terms and definitions. I would recommend Arno for ITIL training.
