Our Guides

We are not your traditional tour guides.

Big Onion has the finest group of tour guides in the city. Most of us are full-time graduate students researching and writing doctoral dissertations in history. Big Onion guides have high school or college teaching experience and are quite often researching topics relevant to the tours they are leading.

All our guides work exclusively for Big Onion and have completed our rigorous in-house training program and are licensed by the New York City Department of Consumer Affairs. Our guides are passionate about the history, architecture and people of New York. We have been called “brilliant”, “hilarious”, “outstanding”, and “irreverent”. Most of our guides, upon completion of studies, move on to successful teaching careers.

After completing her BA in American History at New York City’s Barnard College, she moved to DC to pursue her doctorate. It did not take long for Tamar to miss the sights and sounds of New York, and so she returned to Brooklyn in 2012 to complete her dissertation in the epicenter of American immigration and urban life. Proficient in both Modern Hebrew and Yiddish, Tamar loves to uncover the layers of history of New York’s diverse ethnic, religious, and cultural communities.

Theodore Barrow

Theodore is a PhD student in Art History at the Graduate Center, CUNY, studying strands of European art and architecture in late 19th century America. Long before this, he was bewildered by the space of Los Angeles, where he received his BA from Occidental College. He promptly moved to New York in 2002, and has explored nearly nearly every corner of this fantastic city on foot over the last decade, and is eager to share his findings. Favorite neighborhoods are the Lower East Side and the ENTIRE West Side of Manhattan, from 59th street to the Cloisters.

Zachary’s research focuses on the environmental history of colonial North America. His other academic interests include the Atlantic World, Native American history, and the African Diaspora.
