Christopher has called New York City home since 1989, combined with over 15 years living, studying, and working in Europe and the Middle East.  Having been an expat in 7 countries, he knows how important it is to make guests feel welcome in an unfamiliar city.  This motivates him to share his knowledge of New York City with others, and he wants to help all visitors gain unique insight into special places in his favorite city.  Christopher has a PhD in history from Columbia University, has worked for universities and educational non-profits around the globe, and is interested in cultural and intellectual exchange, especially through education, cuisine, and travel.
