What customers say about us
“I wanted practical tips to give a better presentation as well as some tips & tricks to be able to control nerves when speaking in front of an audience. And this in both English and Dutch. My expectations were met 100%. I was immediately able to put the tips into practice and I am certain that my presentations will make a much better impression with our target group. ”
“My learning objective was to gain a structured understanding of the approach to guiding colleagues in in telephone calls. My expectations were fully met. First, I was given tools to better manage conversations. Second, I gained insight into what I was already applying myself in a conversation. Thirdly, the interaction was very valuable. Keep up the good work!”
“I really enjoyed the way the training was given. The trainer makes the workshop engaging and he is able to keep everyone's focus. I especially remember that it is important not to bring the content in a negative way but rather to phrase it in a positive way and focus on what is important.”
“I myself and our Customer Programme Team at Snecma Services Brussels were delighted with Jerko's intercultural communication training. The course was interactive and creative. It surpassed the simple do's and don'ts and offered an in depth insight into what communication all together is about. I am confident we'll be a better service provider after having enjoyed this training session.”
“It was a great course. I am convinced that everybody returned back home with a high degree of satisfaction and packed with a bag full of tools for their professional and personal lives. Many thanks for the teachings.”
“Lies Martens combines great expertise and experience with a warm personality and great empathy. The group immediately felt at ease and received excellent advice. Through many practical exercises, we were immediately given actionable and very useful tips.”
“Initially, I was very sceptical about the set-up and was actually swept along in a fascinating story from the start, giving me a clear idea of what can be gained from such performance appraisals. The approach made it clear that you can extract a lot of interesting and useful info from such an interview and apply it immediately. I learned that a performance interview is not a snapshot, but should be a continuous process. As far as I am concerned, this was a very successful workshop.”
“Team building went extremely well. The workshop was very interesting and interactive. The expert sensed our group very well and kept focus on our objectives of ‘active listening and cooperation’. In any case, the workshop flew by!”
“I wanted to gain insights into our team's thinking and thus improve collaboration. There was a nice balance of theory, practical examples and exercises. Each HDBI profile was discussed in detail so we now have a better picture of our communication, expectations and information processing. The result is that we are more understanding of each other. We definitely want another follow-up training!”
