ROCK THAT MOUTH
my first pronunciation course !
Rock That Mouth is different.
Different and special!
PERSONAL FEEDBACK SESSIONS:
Every VIP member will get a personal, exclusive, online feedback session of 60 minutes, with a tiny but mighty group of 4 people max. I will give you tailor-made tips and tricks to get your mouth up to the next level. VIP PLUS members get 4 Personal Feedback Sessions in total, as part of the 3-month RTM Maintenance Program. All online sessions will be held on a Friday. There are morning and afternoon sessions. Waiting list members get my first choice in my coaching calendar!
WAITING LIST = EARLY ACCESS:
Waiting List Members get early access (we will send you a SUPER SECRET LINK to unlock the shopping cart)! I expect the VIP spots will sell out quickly, so join the waiting list to make sure you can sign up before anyone else! The rest of the world joins on May 23.
HUMOR + EXPERTISE+ BUFFILOVE:
You will laugh and learn (holy moly, so much!) with me through 24 video lessons (with English subtitles) & 24 workbooks – that’s over 4 hours of video and over 120 pages of worksheets! And yes, I also share my bloopers. Just wait. And get the popcorn ready!
IT’S NOT ALWAYS AVAILABLE:
You can only join the program during Launch Week (May 23-29 2022), then doors will close forever!
LIMITED VIP SLOTS:
There are only 12 VIP spaces available in order to give everyone personal feedback in our VIP Feedback Sessions.
4 TYPES OF MEMBERSHIP:
Standard (3 months access), Lifetime (Lifetime access), VIP (Lifetime access + Personal Feedback Session), and VIP PLUS (Same as VIP but with a 3-month Maintenance Program which includes a monthly Personal Feedback Session). There’s something for everyone!

Why me?
- Because I’ve been there. Lots of times.
- I know exactly how it feels to worry about your pronunciation in another language.
- To feel small. To feel ashamed. To feel stupid.
- I’ve learned 6 languages and failed along the way.
- I’ve asked for circumsized bread in Dutch.
- I’ve showered with ham instead of soap in Spanish.
- I’ve said someone was dead instead of single in Czech.
It’s a horrible feeling to feel stupid when you are not. I don’t want anyone to feel ashamed of their English pronunciation. So…. let’s beat the shame game and get rocking!

I’ve spent 30 years as a Personal English Coach, helping highly-motivated people feel fabulous in English.
I’ve been honored to coach some pretty awesome artists, like Jeangu Macrooy, Danny Vera, Anneke van Giersbergen, Jandino Asporaat, Tim Knol, Racoon, Epica, Within Temptation, Monic Hendrickx, Jacqueline Govaert, and so many others.
I’ve helped them with their English pronunciation, so that they can sing, act, present, and perform with confidence and ease! Buh-bye English stress! Don’t let the door hit you on the way out! You’ve also seen my coaching work in movies, like Brimstone, de Dirigent, and April, May, and June, where I’ve done accent reduction for the leads.
