Sabrina Mattle is a psychologist from Liestal, Switzerland and is working in her own practice for sport, performance and health psychology. During her studies she completed a further education in hypnosystemic communication at the Milton Erickson Institute in Rottweil under Bernhard Trenkle. This experience motivated her to continuously immerse herself into the practical and scientific application of hypnosis. In her first research work, her strong interest in sports psychology and hypnosis led her to focus on the effect of hypnosis on the performance in shooting sports. Further interests are in the fields of performance and health psychology.
