“With a discerning and diagnostic ear, Kathrin went profoundly deep to the place I kept my voice masked by adverse emotions. Through a gradual process, she has guided me in understanding how sound is vocally produced while helping me to internally relax. Her lessons have helped me shed light on my own capabilities, which she does with a forthright, sincere approach while communicating her messages with precision and clarity. In training with other coaches (teachers), not one has come close to being such a fine vocal technician. Kathrin is a passionate, talented vocalist and astute professional that I feel fortunate to have found.” Susan Schwartz, Stuttgart
