While training on the U.S. team, Jack has been sponsored by the New York Athletic Club, the spiritual home of elite sport in the United States, and is proud to represent the winged foot on the national rowing team alongside an incredible group of U.S.A. athletes in a range of sports. For five years, while completing his doctorate at Oxford University, Jack trained under coaches Henry Bailhache-Webb and Richard Spratley at Oxford Brookes Boat Club (and its affiliated club Taurus Boat Club).  Brookes is a High Performance Centre for the British team and, along with Leander Club, one of Great Britain's two most successful rowing clubs.  Jack is proud of his connections with Oxford University Lightweight Rowing ClubOriel College Boat Club, where he was made an honorary member of the Tortoise Club after coaching the 1st VIII to two Summer Eights Headships, and Georgetown University rowing.


Jack is grateful to the online wristwatch magazine HODINKEE for their sponsorship, which culminated in historic wins in both the Britannia Challenge Cup at the 2013 Henley Royal Regatta and the Governor's Cup for Championships Eights at the 2013 Head of the Charles Regatta.


Jack is also a life member of Oxford University Boat Club; a full member of Leander Club; and an alumnus of Buckingham Browne & Nichols School rowing (one of the oldest schoolboy rowing teams in the United States).


Jack serves on the Young Executive Board of Row New York, a rowing and academic program empowering young people from under-resourced communities, and on the Board of Directors of the United States Lightweight Rowing Association, a non-profit dedicated to helping the United States win medals at the World Championships and Olympic Games and supporting U.S. athletes in training.  Jack has also hosted book events in support of Row New York and the Stewards' Charitable Trust, which helps young people learn how to row.
