Are you looking for an effective stuttering therapy for adults that goes beyond traditional speech therapy? With the Del Ferro method, you don’t work on accepting stuttering—you work on a permanent solution.
We apply the technique directly to your daily life. That way, you speak stutter-free and with confidence during meetings, presentations, and in your personal life.
Stuttering therapy: what to expect
During the 5-day course, you will learn the Del Ferro speaking technique. By releasing the physical blockage directly at the source, stuttering becomes physically impossible. You will speak 100% fluently and stutter-free from day one.
You speak completely freely and fluently in all situations – from a business presentation to an informal conversation. Through the combination of the physical speaking technique and mental guidance, your self-confidence grows rapidly. From now on, you always say exactly what you want without hesitation or doubt.
Fluent speech becomes the new reality in your life. You experience the freedom to pursue your dreams without restraint and share your opinion freely. Full of confidence, you step into a stutter-free future where no one can tell you ever stuttered.
During the Del Ferro course, you will work step-by-step toward a future free from stuttering and speech anxiety. Discover what you learn in each phase, from the initial 5 training days to phasing out the technique and entering the aftercare program. Click on the sections below to view the content:
On day two, you deepen your speaking technique and experience what it feels like to speak without tricks, substituting synonyms, or avoidance behavior. You consistently apply the Del Ferro Method in various speaking situations, quickly building greater skill and control. Additionally, concentration training is on the agenda to build inner peace and focus while speaking.
On day three, the focus shifts to making the speaking technique invisible. You learn to apply the method so naturally that your calm way of speaking comes across completely effortless. Others hear a relaxed speaker while you discreetly apply the technique. In addition, we dive deeper into the mental side of speaking, helping you break through ingrained doubts and the fear of others’ judgment.
On this day, you apply the Del Ferro method in challenging practical situations. You learn how to effortlessly maintain the technique while giving a presentation to your fellow participants or in a busy environment. By experiencing that you retain 100% control over your voice even under pressure, your self-confidence continues to grow.
On the final day of the week, you put your skills to the test in a relaxed atmosphere. You comfortably conduct a phone call with complete fluency and read aloud without a single hesitation. You celebrate your achievements and the start of a stutter-free life, concluding the week with a concrete action plan to continue applying the method in your daily routine.
During two phase-down sessions, you learn the crucial final component of our method: the gradual phasing down of the speech technique. We guide you through the transition from a conscious speaking technique to unconscious, automatic fluent speech. In this way, the technique becomes redundant and conscious effort gives way to stutter-free speech in every situation.
As part of the aftercare program, you have weekly contact with your stuttering specialist and access to bi-weekly drop-in aftercare sessions. With the advanced training ‘From Surviving to Living Freely’, you also mentally release all self-doubt and speech anxiety. In this way, fluent speech becomes a natural, automatic habit—until no one even notices that you ever stuttered.
The stuttering therapy is conducted by one of the following specialists:

I firmly believe in the potential of every participant to overcome stuttering once and for all
As a 13-year-old boy, Patrick experienced the magic of the Del Ferro method. A discovery that not only made him stutter-free, but also allowed him to say goodbye to the insecure version of himself. He felt reborn.
Since 1994, he has been a certified Del Ferro Stuttering Specialist, dedicated to freeing people from stuttering using the method that transformed his own life.

Because of Del Ferro, I Was Able to Practice My Profession!
Because of Del Ferro, I Was Able to Practice My Profession!
I am eternally grateful to Del Ferro, as they truly enabled me to practice my profession!
Years ago, I underwent training at Del Ferro to master proper diaphragmatic breathing, which caused my stuttering and hyperventilation to vanish completely and permanently. Today, as a practicing psychologist, I regularly hear about the outstanding results and wonderful reports coming from this institute. Hats off—highly recommended!

Applying the Technique Consistently Guarantees Success!
Applying the Technique Consistently Guarantees Success!
I struggled with a stutter for years. Both as a child and as an adult, I attended multiple rounds of speech therapy. None of it was successful, and I was repeatedly told that I would never overcome it and just had to learn to live with it. I had somewhat resigned myself to it, but I constantly struggled to convey information effectively, which I found incredibly frustrating.
That is exactly why I chose Del Ferro. From Day 1, I fully seized this opportunity. The training and ongoing support are top-tier.

Stutter-Free for 40 Years: Now Chairing Meetings as Board Chairman
Stutter-Free for 40 Years: Now Chairing Meetings as Board Chairman
Forty years ago, I walked into Del Ferro as a highly insecure young man. Speaking was an uphill battle—sometimes it took me a full minute just to get a single word out. What most people didn’t realize was that I spent years desperately trying to hide it. After years of traditional speech therapy, this institute became the ultimate turning point in my life.
This method completely transformed my life. Not only did I regain control over my speech, but more importantly, it restored my self-confidence. Today, 40 years later, I am 58 and chair meetings as the head of several boards—something I once deemed completely impossible. I wholeheartedly recommend Del Ferro to anyone struggling to speak fluently. Don’t keep carrying this burden in silence; there truly is a life-changing solution.Hans

They Are Truly Exceptional at Helping People Overcome Stuttering
They Are Truly Exceptional at Helping People Overcome Stuttering
Last year, I completed the stuttering therapy at Del Ferro, which was led by Patrick. Afterward, I started working with Dennis in the aftercare program. Beyond being incredibly warm-hearted individuals, they are truly exceptional at what they do: helping people permanently overcome stuttering.
They provide you with the practical tools to take action and truly make a change yourself. My experience with both the course and the aftercare program was highly positive, and I honestly can’t even remember the last time I stuttered!

Del Ferro Also Prepares You for the Misunderstanding and Unrealistic Expectations of a Fast-Paced, Fluent Society
I first came to Del Ferro as a 13-year-old. By applying the method, my speech became increasingly fluent! However, at the time, it truly felt like a high-performance sport: consistently putting it into practice around my peers was quite a challenge.
Recently, I decided to return to the Del Ferro Institute for a film project focusing on young people who stutter. I was struck by how Patrick’s passion and enthusiasm remained completely unchanged. He shared openly how the program has evolved over the eight years I had been away. During my shadowing days, I noticed that the actual challenges faced by stutterers and participants are fully acknowledged and addressed during the course—something I personally view as an essential addition.

Del Ferro Comes Highly Recommended If You Are Truly Motivated to Speak Stutter-Free
Two years ago, I completed the stuttering therapy program to permanently overcome my stutter. It was an intensive but incredibly rewarding week. However, the real journey truly begins in the period after the course, when it comes to consistently applying the technique in daily life.
The ongoing guidance has always been outstanding, and the trainers are always welcoming to any questions. The periodic updates—a perfect moment to pause and evaluate progress—along with the highly actionable feedback and practical advice from the team, are incredibly valuable. Thanks to this program, I now speak with absolute confidence.

After 46 Years of Stuttering, Del Ferro Stuttering Therapy Opened My Eyes
After 46 Years of Stuttering, Del Ferro Stuttering Therapy Opened My Eyes
In early July, I completed the intensive 5-day training program, followed by 3 aftercare days. We had a wonderful group and were guided by exceptionally knowledgeable and enthusiastic trainers! After 46 years of living with a stutter, this course truly opened my eyes, and my speech has improved significantly ever since.
I haven’t fully reached my goal yet, but by committing to the daily exercises and consistently applying the technique, I am making massive strides every single week. They strongly emphasize that there is ultimately only one person who can transform your speech, and that is you. In my opinion, anyone who struggles with a stutter should absolutely turn to Del Ferro!

The Del Ferro Method is recognized worldwide as one of the most effective therapies for adults who want to stop stuttering.
Unlike regular speech therapy, Del Ferro focuses on the physical cause of stuttering: uncontrolled movements of the diaphragm. By mastering this speaking technique, you learn to speak fluently in a short time, until the moment that no one can tell you ever stuttered.
With Del Ferro, the results are immediately noticeable. During the 5-day course, adults learn to apply the speaking technique directly in practical situations.
All participants speak stutter-free right from the very first day of the course.
Yes, Del Ferro’s stuttering therapy is partially covered by various health insurance providers.
We recommend checking with your specific provider for details.
Absolutely. Our training focuses on the physical cause of speech blockages, which directly reduces public speaking anxiety and builds the confidence needed to overcome social phobias.
Because the Del Ferro Method gives you a 100% reliable technique to fall back on, your self-confidence grows rapidly.
The fear of blocking disappears as soon as you realize you have regained control over your diaphragm and, consequently, your speech.
While traditional speech therapy often focuses on a lengthy search for the underlying (psychological) causes of stuttering, Del Ferro consciously chooses a different path. Without discounting the value of speech therapy, we do not believe in endlessly looking back.
At Del Ferro, we don’t look for the ‘why’, but focus directly on the ‘how’: how do you release the physical blockage and how do you speak fluently again from day one? Our approach is purely practical, focusing on training the diaphragm muscle and building mental resilience in the here and now.
Discover the Power of the Unique Speech Technique
Taking the first step can be nerve-wracking. With us, you are in a 100% safe environment. No heavy psychological sessions, but a direct introduction to the unique speech technique that instantly restores control over your voice. Within 30 minutes, you will know exactly how it works.

For years, I consistently avoided the media due to my stutter. It held me back from being who I truly wanted to be. Thanks to the Del Ferro Method, I experienced the ultimate breakthrough. Now, I give stutter-free interviews and stood with full confidence on a packed Coolsingel. Stuttering doesn't have to be a lifelong problem—I want to motivate everyone to show who they truly are.
