Katja is a gifted teacher who cares about the music as much as she cares for her students. She has an excellent balance between rigor and kindness, allowing her students to make regular progress in a warm atmosphere. She is also an exceptional classical and jazz performing artist, which is a wonderful source of inspiration for her students. I have very high standards in music education, my only regret is that we have not found Katja earlier. It is a true privilege to have a musician of this caliber teaching my child. Yaniv Sabbah
