Overview
Jennifer Loeb is a partner in Steptoe's Investigations, White Collar, and Compliance practice, where she represents multinational companies, boards, and senior executives in their most sensitive government investigations, internal investigations, regulatory enforcement matters, and crisis situations. A former senior federal prosecutor and accomplished trial lawyer, Jenn's clients rely on her to guide them through fast-moving matters that sit at the intersection of enforcement risk, regulatory exposure, and institutional reputation. They report to Chambers that "Jennifer is simply amazing, she is responsive, always on point and understands our reality and needs."
Jenn recently served as a Senior Assistant United States Attorney in the Sex Offense Unit of the US Attorney's Office for the District of Columbia, where she tried dozens of cases, examined hundreds of witnesses, and presented the testimony of forensic, scientific, and social science experts. She also drafted more than a dozen appellate briefs and argued before the US Court of Appeals for the DC Circuit and the DC Court of Appeals.
Jenn advises clients facing regulatory scrutiny across a range of industries, often before a formal investigation has been opened. She helps companies assess risk, manage government inquiries, respond to investigative demands, and coordinate strategy across parallel proceedings. Her practice includes representing clients in matters involving consumer protection, fraud, compliance, technology regulation, child safety, and emerging enforcement risks.
Jenn also regularly leads sensitive internal and independent investigations involving allegations of financial misconduct, interpersonal misconduct, compliance failures, and conflicts of interest, among others. Her background as a sex-crimes prosecutor, including years spent working directly with hundreds of victims of sexual misconduct, gives her particular credibility and judgment in the most sensitive of these matters. Jenn also brings valuable in-house experience to her investigations practice, having completed a one-year, in-house secondment with a global natural resources company, where she worked alongside senior legal leadership on compliance and investigations matters.
Since 2025, Jenn has built a DEI enforcement advisory practice from the ground up, counseling companies on regulatory risk, government certification inquiries, workforce policy, and investigation readiness as enforcement priorities in this area have rapidly shifted. She has counseled dozens of clients on DEI compliance and has spoken on panels in Europe and across the United States, United Kingdom, and Asia.
Outside of her core practice, Jenn maintains an active pro bono docket. She serves as counsel in impact litigation and appellate matters focused on gun violence prevention, including amicus briefs defending assault weapons bans and restrictions on large-capacity magazines. She has counseled several non-profit and religious organizations and represented individuals in immigration court proceedings.
