Meet David Avrin—a former a capella singer with “The Diners” who traded harmonies for a global stage, speaking in 28 countries to teach companies how to create brilliant customer experiences. From his roots as the second of six kids with a rocket scientist dad who photographed Mars, to building a life with his wife, three kids, and two cats. David’s journey is packed with hard knocks and challenges us to “live your dash” between the dates on your tombstone.
