Christopher Trombley

A resident of New York City since 2008, Christopher moved from his hometown of Ann Arbor Michigan to escape the oppressively cold winters there. A lifelong cyclist and career cycling advocate, he has served on the board of directors for the New York City Mountain Bike Association and currently serves as its director of programming.

Christopher was drawn to OSA by its open, welcoming community, and his fascination with all things old keeps him duly entertained while maintaining the property at OSA.

He enjoys playing the trumpet, welding, cooking, and spending time with his wife and two kids in what he calls “the best neighborhood in all of NYC” -Washington Heights.
