FORT LAUDERDALE, FL - Rossen Law Firm, a premier South Florida criminal defense firm, has expanded its leadership team with the addition of Abigail Rae “Abi” Langweiler, Esq., who has joined the firm as Managing Attorney.
Langweiler brings fifteen years of experience in indigent defense, serious felony litigation, and team leadership. Most recently, she served as Deputy Managing Attorney for the Office of Criminal Conflict and Civil Regional Counsel in Florida’s 4th District, where she supervised lawyers handling life-punishable and other high-stakes cases and helped build an intensive law-student internship program.
“Abi is a true power hitter in the criminal defense world,” said Adam Rossen, founder and CEO of Rossen Law Firm. “She’s tried serious cases, led attorney teams, built internship and training programs, and done it all with a deep commitment to people who are often overlooked by the system. Bringing her on as Managing Attorney raises the bar for the service we can provide to our clients across South Florida.”
Langweiler said she joined Rossen Law Firm because of a shared belief in holistic, client-centered defense. “I made the decision to join Rossen Law Firm because I want to focus on a truly client-centered, holistic approach to defense,” she explained. “Our clients have whole lives outside the courtroom, and our work has a ripple effect on them and their families. I wanted to be somewhere that gives me the time and support to really invest in that.”
Over the course of her career, Langweiler has first-chair experience in hundreds of cases, from arraignments through jury trials, making her skilled in complex motion practice, investigations, and collaboration with expert witnesses to dismantle the State’s case. She is known for developing creative defense strategies, collaborating closely with experts and investigators, and connecting clients with community resources that support long-term success. She is equally proud of her work mentoring young lawyers and law students who are committed to client-centered defense.
“Defense work is about big wins and small wins,” Langweiler added. “Sometimes it’s a dramatic trial result, and sometimes it’s helping a client get the support they need, so they never see the inside of a courtroom again. Both matter, and both can change the trajectory of a life.”
Langweiler is admitted to practice in Florida and New Jersey. She earned her J.D. from Nova Southeastern University Shepard Broad College of Law and her B.A. in Journalism from Ithaca College. She lives in Boca Raton with her husband and two daughters.
