Intercultural Communication & Collaboration

“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.”

What customers say about us

Elevator Speech

“I wanted to be able to deliver a message more efficiently and with greater conviction. My expectations were 100% met. This was a very good training. Particularly interesting was the structure of a message, such as not starting immediately with the 'what' but focusing on the 'how' first.”

Conflict Management Training

“The course was really good and complete, with a really nice and dynamic trainer who led the discussions very well, gave relatable examples, and kept the times while enabling everybody to contribute. The workshop gave me tools to apply in case of conflicts at work but also in general.”

Business Writing Skills

“I wanted to learn to write emails in an even more customer-friendly way. In addition, it was important to get the necessary tools to write texts for the web and for newsletters in a creative way. This expectation was completely fulfilled thanks to the useful tips and the practical exercises. I still take the syllabus with me when I write texts.”

Negotiation Skills

“During this very successful training I was able to master the basics of negotiation as well as being given a number of ‘capstans’ to use during negotiations. The tips on body posture and maintaining rapport during conversations were extremely valuable. These expectations were met and I got the chance to see my own skills but also weaknesses during the workshop.”

Consultative Selling - Sales training

“The trainer managed, in a practical way, to teach me useful things. The importance of asking open questions in the sales process and daring to adopt an assertive attitude. I can now apply this on a daily basis. The training has really flown by. It was a great learning experience! ”

Communication workshop

“The communication workshop was way better than expected. It really made all my employees open up and get to know each other better. It was also very interactive with a lot of exercises and techniques. We now have learned a structured way how to give feedback to each other and to customers.”

Prevention of stress and burnout

“In this course I learned how to better deal with certain stress factors that are out of my control. The workshop was very to the point and very informative. It is the most interactive training I have ever had and with a super teacher. I have the feeling that I will be able to benefit from this for a long time to come.”

Successful prospecting

“I really wanted to know how to turn a ‘no’ into a ‘yes’ during a phone call for an appointment. Through practical exercises and the formulation of possible counter-answers, this was immediately put into practice. I also gained insight into a clear structure of points to follow during telephone prospecting. I am impressed by both the positive teaching style and the trainer's knowledge.”

Voice coaching and pronunciation techniques

“For many years I have been struggling with speaking fast and articulating poorly in Dutch. The coach provided good insights and the exercises and tips are a daily reminder to pay attention to my breathing. I also received some personalized tips that are very helpful. I should have done this earlier!”
