Justin Keith Gelfand

Justin Gelfand, a founding partner of Margulis Gelfand, is a former federal prosecutor with extensive experience in high stakes litigation. Justin's clients have included IRS whistleblower/former acting IRS commissioner Gary Shapley, actor Terrence Howard, reality TV personality Josh Duggar, former Congresswoman Cori Bush's husband Cortney Merritts, "Chimp Crazy" TV personality Tonia Haddix, political activist/television correspondent Jack Posobiec, and former political officeholders.

National media outlets have described Justin as a “powerhouse” litigator and “high-profile” attorney. Opposing counsel described Justin’s cross examination of a critical witness as “merciless.” On the record, a federal judge described Justin’s advocacy as “quite special” and “an eye opener.”

Justin, a member of the Teaching Faculty of Harvard Law School’s Trial Advocacy Workshop, is at home in the courtroom and routinely tries cases to verdict. But when it’s in his client’s best interest, Justin resolves cases outside of the courtroom—often with no publicity.

Justin routinely presents continuing education to attorneys throughout the country on cutting-edge legal issues. Justin served as a faculty member at the National Advocacy Center, the Department of Justice’s in-house training center in South Carolina, where he taught hundreds of federal prosecutors the ins and outs of criminal tax cases. He played a large role in crafting the innovative manner in which stolen identity tax refund fraud cases are now investigated and prosecuted, and trained more than 1,000 federal agents in 15 states concerning investigative techniques used by law enforcement. For this work, Justin received the Attorney General’s Award for Fraud Prevention, an award widely recognized as one of the Justice Department’s highest honors in white collar and public corruption litigation.

In addition to teaching at the Trial Advocacy Workshop at Harvard Law School, Justin has served as an adjunct professor of law at Washington University in St. Louis.

Justin graduated in the top 5% of his class at Washington University School of Law and was inducted into the Order of the Coif. During law school, Justin was a Senior Editor of the Washington University Law Review and competed on the law school's flagship National Moot Court Team.
