Sara Kropf


Sara is a trial lawyer who defends people under criminal investigation and companies in complex civil litigation. Her criminal practice focuses exclusively on white-collar criminal defense work, with substantial experience in public corruption, antitrust, and government contracting matters.

There was never any doubt growing up that Sara would be a lawyer. According to some very unreliable sources (her parents), she was a stubborn kid. She was also a nerd.

Sara’s persistence and nerdiness turned out to be useful traits as a lawyer. She does not give up on her clients when the odds of success are long and loves to dive into thorny legal issues. Because every one of her clients is facing a crisis when they call, Sara knows that they need more than a lawyer. Her approach combines tough lawyering with a sympathetic ear and a healthy dose of keep-you-sane humor.

After law school, Sara paid off her student loans by joining one of the biggest law firms in the country. She ended up loving the complexity of the work and stayed for ten years, eventually making partner. She represented large companies and executives in complex criminal investigations and litigation. Sara took cases to trial in federal and state courts across the country.

After ten years at a big firm, Sara realized that she wanted a different path. She loved the practice of law but wanted to represent people and small companies. A big firm’s price tag put that out of reach for most of them. So, in 2013, Sara founded a solo law firm that eventually grew into Kropf Moseley PLLC.

Sara is a Fellow in the American College of Trial Lawyers, which means that a courtroom feels like her second home. If push comes to shove, Sara is prepared to take her client’s fight to the end.

Sara has lived in Washington, DC for over 30 years and raised her two sons in the city. She is a huge fan of the Washington Nationals, the Fourth Amendment, and the Oxford comma.
