Jennifer, a former federal prosecutor, is a skilled trial and appellate attorney, experienced in litigating cases involving healthcare fraud, money laundering, deprivation of civil rights, and customs, tax, and RICO violations.

With a results-oriented mindset, she is a strong, passionate advocate for her clients.

Before entering private practice, Jennifer served as an Assistant United States Attorney for nearly eight years, having been hired through the nationally competitive Department of Justice Honors Program. While at the U.S. Attorney’s Office, she tried numerous jury trials, argued several cases before the Ninth Circuit Court of Appeals, and directed a wide variety of grand jury and wiretap investigations. Jennifer served as a deputy chief, supervising a team of prosecutors, and as a Department of Justice faculty member for the National Advocacy Center. She trained agents and prosecutors, both nationally and internationally, about substantive and procedural criminal law. Jennifer was the recipient of numerous awards, including the prestigious Department of Justice Director’s Award, presented by the Attorney General in 2015.

Immediately following the U.S. Attorney’s Office, Jennifer was a name partner at a litigation boutique for two years, where she defended numerous clients in government investigations and prosecutions. She went on to form Summa LLP, a law firm dedicated to authenticity and to practicing at, and from, the highest level.
