I approached Isabelle to improve my English pronunciation. Although I have a good understanding of the language and a broad vocabulary, I hadn’t learned proper pronunciation and phonetics. When I moved from South America to the Netherlands for work, I realized that people had trouble understanding me, and I felt insecure about speaking because I wasn’t confident in my pronunciation.

Regarding the learning process, the book we used was very helpful, and the exercises to learn to hear the differences between my pronunciation and that of native speakers, especially the vowels, were particularly useful. Some concrete results were that I significantly improved my pronunciation over a period of six months, which has given me more confidence to speak in a professional setting and give presentations. Of course, constant practice and speaking up are also important for progress.
Isabelle is a very kind, flexible, and empathetic person, which makes it comfortable to talk to her and share frustrations and achievements. She always finds ways to adapt to specific needs and requests. I highly recommend taking classes with her.

I loved getting clarity on my story and being able to fully be myself in the process with Isabelle. She really sees you and always has amazing feedback and edits to make things more tangible and be more on point. Writing your one story is an emotional project. We want to trust the ones who we share a new version or angle of our story with fully. Isabelle is the one for me, who I can trust and experience my stories with. Most valuable, I feel I created a great base for my signature stories and confidence to be able to weave them naturally into any context.

After the first session, she motivated me positively, encouraging more eye contact with interviewers and enabling me to express myself comfortably. She supported me a lot during this process, helping to clear all the question marks in my head. I thank her for her support on this path. I am very lucky to have crossed paths with her. If you are looking for a good coach, I would definitely recommend her. It's not over yet, and I'm sure I'll have the opportunity to work with her again.

Isabelle van den Heuvel is my turn-to guru when it comes to expertise in the English language. Words that I believe define Isabelle are ‘expert’, ‘results-driven’ and ‘warm’.
I have always admired her fluent, easy-to-read and easy-to-understand style. It is a joy to observe the effortless way in which her sentences flow. It is generally recognised that bi-lingual speakers often have a preferential language; this is not so in Isabelle’s case.
