“Buffi helped me to achieve a good level in business English. Her enthusiasm, professionalism and creativity are so inspiring. She also had a very good understanding about my business, not only including my work as an artist for radio and television, but also as a moderator for international corporate events. Buffi is one of a kind and an absolute joy to work with.”

Diana Matroos

“What a great voice-coach and quite frankly wonderful woman Buffi is! I Love Buffi! She is one of those teachers you wish you had in high school: funny, witty and super duper critical on your pronunciation, but in a good way! All to help you grow your ability to speak amazing English. We had a great session. You immediately feel at home with her, Its a bit like reconnecting with an old friend, but one who is just really serious about your language! 😉 Buffi lets you fall in love with your English all over again! Highly recommended!”

Jakob Krabbé

Allround Voice-Over Professional

“Buffi is an artist with words in the English language. If you think she cannot improve your English, think again! It should be mandatory for non-native English speakers to have their speeches, TED Talks or otherwise, screened by Buffi. We would all benefit! I truly rocked my TedxWomen talk! Thanks, Buffi!”
Prof. Lokke Moerel

International Cyber Security Lawyer and Advisor

“Buffi asked me this question in my first meeting with her: “How many words you can think of instead of ‘good’? I came up with ‘great, awesome, fantastic, super, nice….’
Now I understand that you wanted me to describe you as a person. Thanks so much for helping  me as a person but we are not finished yet….!”
Mike van Tilburg

​“Buffi’s coaching is straight from the heart, direct and fun. She helped me formulate the essence of my lifes work for my TEDtalk and her encouragement all the way on stage gave me the confidence that I needed to share my story in English. She had my back 100% ❤ Thank you Buffi!”

Jessica Gyasi

“I needed to be confident to speak in front of large groups. This was easily achieved with such a wonderful coach.

Merijn Everaarts

“I have not regretted the day I chose Buffi for my English coaching. What a great coach! She is so energetic and has such a big and warm heart. I love her way of coaching and she has helped me tremendously in such a short period of time,  and she combines that with lots of fun. I was so nervous to speak in public, and it’s not only much easier now – I really enjoy it! Many thanks Buffi♥”
