Daniel also interned at the Antitrust Division of the U.S. Department of Justice and for Judge Victor A. Bolden on the U.S. District Court for the District of Connecticut. Prior to law school, Daniel served as the founding chief of staff of NYC Kids RISE, a nonprofit that automatically opens and funds college savings accounts for every kindergartner in New York City public schools as a tool for wealth-building and educational opportunity.

"My proudest moment as a plaintiffs’ attorney was assisting Keller Postman in its victory at the U.S. Supreme Court on behalf of Robert Mallory in Mallory v. Norfolk Southern Railway Co. That case represented many of the things that I find most rewarding about plaintiffs’ lawyering: it raised a complex issue that required significant legal and historical research, it could not have been won without creative and rigorous advocacy, and the outcome helped to level the procedural playing field between plaintiffs and corporations.
