Zachary Macdonald

Associate

Zach joined Keystone in 2024 as an associate in the Boston office. He graduated from the University of Massachusetts Amherst with dual degrees in Economics and Philosophy and a minor in Chinese.

While in school, Zach consulted on projects for Fortune 500 clients and a large private research university with the Isenberg Undergraduate Consulting Group, conducted research on economic statecraft and Stoic metaphysics, and played goalkeeper for the club soccer team. He was drawn to Keystone by the prospect of merging his interests in law and economics within its unique academic environment.

Outside of work, Zach splits his time between couch-potato and active endeavors—the former including reading science fiction and watching movies in languages he’s trying to learn, and the latter encompassing hobbies such as Muay Thai and backcountry camping.
