The contents of the training

The training is given by officially educated Del Ferro teachers. Many of whom have stuttered and have conquered stuttering by using the Del Ferro Method themselves. Next to overcoming the stutterproblem, the finishing of fear and the construction of self-confidence, it is especially a very practical training in which fluent speech is trained intense.

The Del Ferro Method is built up in 2 phases

In level 1 you learn the basic Del Ferro technique and situations are trained like making a telephone call, read out loud, having conversations, speeches and giving presentations. You undertake all the speech situations in which you could have stuttered in the past. Guaranteed that all these situations will be fluent by means of the Del Ferro technique! Of course there is being given an extended attention to the Del ferro breathing technique.


The technique is not only trained during the day but also after the lessons at the end of every course day. A big advantage of this is that you exercise in ordinary situations in which you stuttered before. In this manner the fear to speak and avoidance changes into self-assured and purposeful behaviour so that self-confidence gets a boost by the day. You can participate the course in a group but there is also a possibility for our private training.

In level 2 you get insights in your own behaviour and the technique is being brushed up. Level 2 emphases on the mental aspect. You can have fear of failure or you can have a doubt whether you are going to succeed or not. Perhaps you are to occupied being interested in the opinion of other people or you are too hard on yourself. You learn how to rely on yourself even more so that you keep on speaking fluent in every situation with confidence.

In level 2 you get your lessons from Eva Wolf. Eva is a psychosocial therapist, NLP-master and mindfulness trainer.

In addition The Del Ferro Method has the advantage that the physical condition and endurance is  being improved. It has a very positive effect on the psysical condition and recoverance during psysical strain of athletes. Due to this technique the lactic acid level in the blood actually reduces. Because of this you feel less rapidly tired and you recover faster after a psysical strain. The Del Ferro Method is also the solution for burnout symptoms, hyperventilation and other breathing related problems.
