Incredible transformation - Tools that make an impact

We’ve seen an incredible transformation in our son Andre since working with Del Ferro. Both on the tennis court and at school, his negative self-talk and reactions have drastically decreased, and he’s now able to reset his emotions much more quickly.

The tools he learned help him calm himself, stay centered, and find his own solutions in challenging moments. As a parent, seeing him gain that confidence and emotional control has been truly life-changing.

This work is done with so much kindness and without judgment, and it truly makes a meaningful difference in the lives of kids and their families.

This could actually work (and probably will)

I am training for 2 days now, the first times in my live i didnt stutter (with method ofcourse) and as i progress in this course the more i think: this might actually work! And because my teacher stuttered before too makes me more confident that this is gonna work!
And no it is not magic, you will need to 'work' for it. but once you keep on training i think is going to work, simply because it sounds logic that you can 'reprogram' your diaphram to work smooth!

The method was good 20-30 years ago…

The method was good 20-30 years ago because there was nothing better available.
It used the "Lucky fluency" phenomenon which did work for some people.
However, "lucky fluency" can be accomplished with other stuttering therapies as well.
The problem with this is that for most people, the initial fluency doesn't persist despite training as instructed, and stuttering gets worse.
The Del Ferro institute's strict slogan "If you use the Del Ferro method, you don't stutter" is wrong and leaves a bad feeling of failure on the client's side if they did as instructed but didn't maintain their fluency anyways.

Ingrid DelFerro simply wants to continue her father's method without enhancing it with any newer proven sciene in stuttering therapies and now well understood stuttering mechanisms.

My stuttering improved very much for around 1 year. That was the best time of my life. However the psychological "crash" afterwards was horrible as I did my best but couldn't maintain fluency.

Now I use fluency shaping which sounds more alien than the Del-Ferro method but gives me very good control over my speaking while I have no control over my speaking with the Del-Ferro method.

I wish for clients that Ingrid Del Ferro would open up to proven sciene.

Ingrid's father would have appreciated it as he was a scientist person and not a "maintainer".

Dear P,
Thank you for sharing your personal experience. Many of our students share their experiences with the Del Ferro method to support and motivate their journey. For us, it also offers valuable insights into the continuous improvement of stuttering therapy.
Since your participation 20-30 years ago, we have implemented many improvements. Our course groups have been deliberately made smaller, which allows for more personal attention and guidance. We also pay much more attention to the mental and social aspects of stuttering, because we understand that this is an integral part of effective therapy.

In addition, our students learn a specific speaking technique from day one that is immediately applied in practice. As a result, we have already helped more than 13,000 people to become stutter-free, and every person who achieves this makes us extremely quiet and grateful.

We would like to invite you to experience for yourself what our training looks like today. You are very welcome to attend a training in Amsterdam for a day or part of a day at a time that suits you. You can find all contact details on our website.
