Ulrich Kohler (born 1970), a naturopathic practitioner who has been working therapeutically and advising in his own naturopathic practice since 1995, discovered the so-called unconscious guilt and the way to solve it in 2006, many years after an early painful experience. After several years of research into the psychological background, he developed the LösUS® technique and LösUS® therapy. Kohler organizes workshop days for self-application of the LösUS technique and offers in-depth training to become a LösUS® practitioner.
