As an associate on the investment team at Castanea, I have the opportunity to delve into the inner workings of growing brands and meet the energetic founders behind them.

I also work directly with our portfolio companies Essentia, Jeni’s Splendid Ice Creams, 4moms, and Brew Dr. Kombucha.

Prior to joining Castanea, I worked at Morgan Stanley in the Firm Strategy and Execution group, advising clients on M&A and corporate strategy. An economics major at Harvard University, I rowed with the varsity lightweight crew team and ran operations for the university newspaper. Originally from upstate New York, I enjoy exploring the outdoors and getting together with my five younger siblings.
