Since 1987 I've indulged my passion for New York by giving classes, lectures and tours of its history. We go beyond the usual who-what-where-when and into the why and how. The Museum of Natural History, the Municipal Art Society and New York University are among those who have sponsored my tours. 

Some of these presentations concern the links between the history of New York and that of baseball. This is the topic of the book I'm writing now.

I am a member of the bar, the former director of a Manhattan nonprofit and a registered New York City tour guide.
