"For Daniel Zumbach, I gave him only the best mark. A patient driving instructor who gives you courage, stays calm and is well prepared for the exam. Gives you the security to pass the driving test for the cat.D I always felt safe and well taken care of with him. Wish him all the best and many more learner drivers. R. Knutti "
