David is a man of many hats. They don't all match his socks, but he likes to think that taken together they do complement each other for an overall wonderful effect. He has a Jewish thought hat, which has seen him complete a PhD in Jewish history and philosophy at Cambridge, where he co-founded the U.K.'s biggest academic Jewish thought conference, and which often finds him lecturing at Jewish institutions around the world. A hat of a slightly different color, led him to study for smichah at Yeshiva University. He also has a very different 'problem-solving' hat, which he is currently wearing during working hours at a leading management consultancy firm in Tel Aviv, tackling problems and advancing innovation for the Israeli government and some of the biggest Jewish and corporate organizations around the globe. Wearing his linguistic hat, David has helped decipher historical German documents that brought back the memory of forgotten Holocaust victims and brought surviving families back together. It has also allowed him to assist Israeli companies penetrate South America, and to lecture at the Sorbonne in Paris. David's collection started in Frankfurt, moved to London, then to Jerusalem, to New York, and has now (most recently) settled in Tel Aviv. Along the way, he also picked other random items of clothing, including a large cape from Cambridge, a brown-belt in Ju-jitsu, some water polo ear guards and a large but currently redundant tie collection.
