Since 1987 I've indulged my passion for New York by giving classes, lectures and tours of its history. Among those that have sponsored my presentations are the Museum of Natural History, the Gotham Center and NYU.

My focus is to go beyond the usual who-what-where-when and into the why and how - simply illustrated, for example, by a bend in a road, shape of a building or site of a church.

Nevertheless, my role is not to load you with information  -  it's to get a few inches of air between your feet and the floor. Maybe that happens once in a while.

I am a member of the bar, the former director of a New York nonprofit, and the author of a coming book on the connections (they're everywhere!) between the history of baseball and that of New York City.
