On this page, you´ll find testimonials, statements of happy customers and clients who hired Ilja Grzeskowitz as a keynote speaker or change consultant for company meetings, association conferences or change programs.



Ilja´s keynote speech was outstanding and everybody felt inspired and valued the authenticity. We especially loved the fact, that Ilja customized his speech with all our wished from the pre-event briefing, and even used some of the content other speakers of the day were talking about. To sum it up: It was a brilliant speech and we already asked him to come back for another one.
Martin Skoda
Head Medical Science Liaison / Biogen
We were all delighted with Ilja – his keynote address/speech was ‘on point’ and exactly what we were looking for. His ‘change message’ was easy to understand for our multi-cultural audience, delivered with good humour and self-deprecation – the attendees loved it! We particularly also appreciated that he took time afterwards and made a real effort to connect with our delegates during breaks and meals for the rest of the day. From first contact, he was easy to work with and his preparation was immaculate, he worked seamlessly with our conference production company and was generally very easy to get along with – a very likeable individual with a good, positive and constructive message. Just what we’d been looking for!
