David was previously an associate at a preeminent corporate law firm where he received significant litigation experience and invaluable mentorship in a broad-based practice. He successfully assisted in litigating a wide range of complex disputes in state and federal courts and in arbitration. His diversified workload highlights included:

  • defending against class-action claims alleging personal and environmental injuries arising from a natural gas blowout off the coast of Africa
  • representing a governmental agency against inverse possession claims stemming from the agency’s large-scale construction next to a luxury residential high-rise
  • litigating on related jury and bench trials arising from a competitor’s improper claimed fair use of the plaintiff’s developed scripts and commands from its software
  • defending against an FTC antitrust merger-investigation under the Hart-Scott-Rodino Act.

Prior to that, David clerked for the Honorable Judge Jill A. Otake of the United States District Court for the District of Hawaii. While there, he attended and assisted with trial and oral arguments, conducted legal research, and assisted in drafting judicial opinions on motions for summary judgment, motions to dismiss, and various other pre-trial motions. During his time in Hawaii, he developed a fond admiration for the Aloha Spirit.

As a law student at the George Washington University Law School, David graduated with highest honors and was an executive editor of The George Washington Law Review. He participated in mock trial competitions, winning the school’s top “Estrella” Mock Trial Competition, along with a classmate, and earning the Best Advocate award. He was also the president of the school’s American Constitution Society student chapter and was recognized as an ACS Next Generation Leader. He participated in his school’s student government and received the Pro Bono Service Recognition Award for devoting a substantial number of hours to pro bono legal work with several different organizations.

David remains deeply committed to providing pro bono legal representation on compelling cases to those who cannot afford it. He has represented Guatemalan refugees fleeing violence and persecution in their claims for asylum, petitioned the government for valuable benefits on behalf of a veteran suffering from PTSD due to a service-related incident, and litigated constitutional excessive force claims against four police officers who had wrongfully allowed a police dog to attack a handcuffed criminal suspect.
