The Del Ferro Method is based on two fundamental principles: diaphragmatic breathing and self-development. This combination provides a powerful and effective approach to overcoming breathing-related issues:
These two principles are combined in a holistic approach. Participants not only learn how to overcome their breathing-related issues, but also how to stand mentally stronger in life. This creates lasting change and a profound impact on participants’ overall quality of life.
The Del Ferro method is a carefully structured process that focuses on overcoming breathing-related complaints through concrete steps. Here’s how it works:
The method starts by teaching the diaphragmatic breathing technique. Students learn how to train their diaphragm muscle, which is essential for healthy breathing.
After mastering the diaphragmatic breathing technique, students are trained to apply it immediately. From the first lesson, this technique leads to a reduction in breathing-related complaints.
During therapy, participants practise breathing techniques during sessions and in everyday life.
The course also focuses on self-development to address negative thoughts and fears, promoting a positive self-image and increasing self-confidence.
The Del Ferro method is very practical as it emphasises practice in everyday situations.
The strength of the method is that when applied, breathing-related complaints are impossible.
Through this structured approach, the Del Ferro method offers a clear path to a symptom-free life, bringing a sustainable return to quality of life.
In 1978, Len Del Ferro, an internationally renowned American tenor, laid the foundations for the pioneering Del Ferro Method. After an impressive international career in opera, he settled in Amsterdam as a vocal pedagogue. He became an influential figure in the Dutch music world by teaching many well-known Dutch artists.
Len Del Ferro was not only a master in music, but also a pioneer in the world of breathing and mental coaching. His innovative approach marked him as the first of its kind in the Netherlands.
Del Ferro’s biggest breakthrough came in the field of stuttering. In the late 1970s, he discovered that stuttering had a physical cause. A discovery triggered in part by his observation that people who stutter can sing fluently but have difficulty speaking. This was a revolutionary insight that went against the prevailing beliefs of the time.
Indeed, it was thought that stuttering was mainly a psychological problem. Del Ferro’s work has fundamentally changed this view.
The diaphragm muscle is normally the silent motor behind our breathing, while in stuttering that muscle appears to make uncontrolled movements. This insight from Len Del Ferro offered not only a new perspective, but also a concrete solution. By training and controlling the diaphragm muscle, you can experience a significant improvement in your speech.
For more than a decade, Len Del Ferro helped hundreds of people overcome their stuttering. Among them was Patrick Wijdenes, one of our current teachers, who had the privilege of learning directly from Del Ferro. This direct transfer of knowledge forms an essential basis for Patrick’s lessons, in which he applies the powerful techniques of the method.
After Len Del Ferro’s death in 1992, his innovative work was diligently continued by his daughter Ingrid. She was heavily involved in his work and played a crucial role in the further development of the scientifically proven breath training. Under her leadership, the Del Ferro method has evolved and is recognized and respected worldwide as an effective treatment for stuttering and breathing-related issues.
Besides solving stuttering, the Del Ferro Method has the added benefit of teaching participants an extremely efficient breathing technique. This not only improves breathing, but also stamina and overall condition and fitness. The result is reduced lactic acid levels in the blood, leading to less fatigue and faster recovery after exercise.
The method also offers relief for burnout complaints, hyperventilation and other breathing problems.
The innovative approach of the Del Ferro method has been extensively scientifically researched and confirmed. Neurologist Dr Van Hemert was the first to test Len Del Ferro’s hypothesis. His research showed that uncontrolled movements of the diaphragm muscle occur in stuttering, which disrupts airflow and leads to stuttering.
That finding has been supported by other leading scientists, including neurosurgeon Dr De Grood and Professor Macklem, an authority on pulmonary physiology. Their studies confirmed that smooth airflow created by controlled diaphragmatic movements is essential to prevent stuttering.
Ingrid Del Ferro has led the Del Ferro Institute for more than three decades. Her expertise and dedication are the driving force behind the institute. Together with a team of expert stutter therapists, she ensures that everyone can overcome stuttering for good with the scientifically proven stutter therapy. Under their guidance, thousands of people have already learned to speak without stuttering from the first day of the course.
Ingrid’s expertise in stuttering and breathing-related complaints has made her a sought-after expert in the media, both nationally and internationally. From appearances on Dutch and German television to interviews by CNN and BBC, Ingrid shares her knowledge and insights on stuttering with a wide audience.
Under her leadership, the Del Ferro method continues to evolve and gain worldwide recognition as an effective treatment for stuttering and breathing-related complaints. With her pragmatic result-oriented approach and empathetic attitude, Ingrid has changed many lives forever.
