For nearly fifty years, Del Ferro has been helping people worldwide overcome stuttering. With the Del Ferro Method, we address stuttering directly at its physical source. Rather than treating symptoms or engaging in an endless search for underlying causes, we provide a targeted technique that breaks through speech blockages and enables you to speak fluently from the very first day of the course.
Physical Foundation and Mental Freedom
The diaphragm lies at the heart of the Del Ferro Method. As the primary breathing muscle, it forms the physical foundation of speech. By regaining control over your diaphragm, you establish a solid foundation for fluent speech.
However, the physical aspect is only part of the solution. Equal attention is devoted to the mental side of stuttering. By combining a physical approach with dedicated mental coaching, you break through the underlying patterns standing in the way of fluent conversation.
From Tension to Self-Confidence
When you experience words flowing effortlessly, the fear of stuttering fades and your self-confidence grows. You no longer have to worry constantly about freezing up. Instead, a steady confidence takes over during conversations and whenever you need to speak or give a presentation.
This creates room to participate fully in life once again—in conversations, at work, during presentations, or simply in day-to-day interactions.
You reclaim permanent control over your voice and your life. The tension vanishes, your confidence grows, and you speak with complete fluency.
At Del Ferro, you don’t learn to live with stuttering, you break through it and overcome it.
Over 13,000 adults and children found the permanent solution through the Del Ferro Method. Today, they speak completely fluently.

I Am a Case Manager Now, Something I Could Never Have Done Without Del Ferro
I Am a Case Manager Now, Something I Could Never Have Done Without Del Ferro
Thirty years ago, I completed the Del Ferro stuttering therapy program, and it completely transformed my life. I used to stutter severely, but within just two weeks, I was virtually free of it. I often read stories about people who experience a relapse in their speech. Fortunately, I never faced that issue because I consistently continued practicing the exercises long after finishing the program.
My self-confidence soared, inspiring me to return to my studies. Today, I work as an Absence Case Manager for the City of Amsterdam. I could never have achieved this milestone without Del Ferro, and I will always be deeply grateful to Ingrid for her incredible guidance!

After just Day 1, I no longer stuttered
After just Day 1, I no longer stuttered
When I contracted an illness that left me severely fatigued, traditional speech therapy failed to help me achieve fluency. Del Ferro was incredibly accommodating of my situation, allowing me to complete the course entirely online and on a 1-on-1 basis. The material was explained with absolute clarity, and Dennis’s firsthand expertise made a massive difference.
After just Day 1, I no longer stuttered. I found that claim hard to believe beforehand, but it is genuinely true. Make no mistake: the training week and the first two months require a great deal of dedication to succeed. However, it pays off a thousand times over.

My Daughter No Longer Stutters Thanks to Del Ferro
My Daughter No Longer Stutters Thanks to Del Ferro
My 16-year-old daughter underwent many years of traditional speech and stuttering therapy, only to be told that she simply had to accept her stutter. When we first heard about Del Ferro, we began to hope that there might still be a way to help her manage her speech—or even overcome it completely.
During the autumn break, my daughter completed the Del Ferro program. It was truly a revelation! She no longer stutters at all. She has become a completely transformed child; it is incredible to watch her self-confidence soar and see her speak so freely. Her opportunities for the future have expanded exponentially.

Still Stutter-Free After 40 Years
Still Stutter-Free After 40 Years
Forty years ago, as a 12-year-old, I underwent Del Ferro stuttering therapy. Prior to that, I had tried multiple rounds of traditional speech therapy with zero results. Thanks to Del Ferro, I am not only completely free from a severe stutter, but the experience also shaped me into who I am today: a true go-getter. Today, I enjoy a successful career in aviation—an opportunity that would have been completely out of reach had I continued to stutter.
I wholeheartedly recommend Del Ferro because of their straightforward, no-nonsense approach and because it is the only therapy proven to help people overcome stuttering and maintain lasting fluency. I am deeply grateful to them for teaching me how to conquer my stutter, a milestone that truly made the life I live today possible.

Six Months Later, Our Son Has Not Stuttered Once!
Our son completed the 5-day stuttering therapy at Del Ferro in 2023. It was a highly intensive week during which he mastered the technique. However, the true work began in the weeks and months that followed. It requires continuous commitment to internalize the method and make it second nature. Throughout those crucial months, he received outstanding guidance to ensure he maintained the technique correctly.
Six months have passed now, and our son hasn’t stuttered once! The method has given him absolute control over his speech and a massive boost in self-confidence.

I completed the 5-day course and it is a very special process. I was taught by Patrick and he knows exactly how to connect with and guide you. Because he used to stutter himself and overcame stuttering through the Del Ferro method, he is very convincing.
You gain more and more confidence in the process and start noticing that you can truly get rid of stuttering through this method. The practice is also a pleasant place to be. After the course, you continue to receive guidance and can contact them with all your questions.

Unlike conventional speech therapy, the Del Ferro Method is fundamentally a physical training program. At its core, it focuses on mastering the diaphragm muscle to eliminate the physical blockage of stuttering.
But the method goes a step further: you learn to speak with complete fluency under pressure in every imaginable situation.
Through these positive real-world experiences, your self-confidence grows, and you will notice that speaking anxiety gradually fades away. Physical control over your breathing creates the foundation for lasting mental peace.
Yes! Our stuttering therapy is suitable for children from the age of 6. Because our approach is purely physiological—focusing on training the diaphragm through the Del Ferro breathing technique—children often grasp the method even faster than adults. It empowers them to immediately speak with confidence again, both at home and in the classroom, without the need for heavy psychological sessions.
The Del Ferro Method delivers immediate results: our participants speak completely fluently from the very first day of the course. You will first learn to consciously apply the unique diaphragmatic breathing technique as a powerful tool in any speaking situation.
The ultimate goal is to speak fluently and for the technique to become second nature. Once the breathing technique is integrated into your system, you will gradually phase out its conscious application. This ensures that, regardless of the pressure you may feel, you will speak fluently and naturally once again.
Yes, every therapist within the institute holds the exclusive title of Certified Del Ferro Stuttering Specialist. Precisely because this method fundamentally differs from conventional speech therapy, our specialists are trained exclusively in-house. The training, continuing education, and peer supervision are among the most rigorous in the field.
