I am an IHK and officially certified dog trainer and behavioral expert for dangerous dogs of the state of Berlin. In my daily business I work closely with veterinarians, scientists and other dogs specialists. I am a member of the Odorology Working Group, which deals scientifically with the spectacular nasal performance of our dogs. Together with my dog Helmut, I live in Berlin and work as a dog expert throughout the German-speaking world. With my knowledge and skills, I was able to secure the title of "Dog Trainer of the Year 2023" in the Sat 1 program “Der Hundetrainer-Champion”.
