Kemmeter, Jennifer: - Jennifer Kemmeter spent her early career working in marketing and economics at a multinational firm. Her twin sons became captivated by Lego(R) products early in life, and as she built models together with them, she was thrilled to see her boys so engaged in a creative and problem-solving activity. As their passion became contagious, Kemmeter began a new career as a designer, author, and publisher of children's books.
