Under Yakir’s leadership, the company has continued to carry on Dr. Ambrose’s legacy. His youth on a kibbutz in Israel, experience as an IDF paratrooper, and extensive travel in the U.S. and Europe have given Yakir a keen understanding of international cultures, travel, and the military. He has applied this experience and knowledge to help earn Stephen Ambrose Historical Tours the reputation for offering the highest quality historical and military tours in the United States and Europe.
