I tell stories and make data useful. My work spans investigative journalism, baseball history, and the art of looking a little closer.

Journalism

From 2010–2023, I was a watchdog reporter for the Rochester Democrat and Chronicle, part of the USA Today Network. I covered public safety and the impact of technology, reported for Gannett papers across New York, and contributed to national USA Today investigations. Earlier, I was a sports reporter and columnist at the New York Sun from 2003–2008.

My reporting on Governor Andrew Cuomo’s campaign fundraising shared the New York State Associated Press Association’s First Amendment Award, presented in 2019. Read the investigation.
