Peter L. Mansmann, Esq., a partner with Precise, Inc., has over 20 years of experience in e-discovery and litigation strategy. Pete co-founded Precise in 2000 while attending law school and working in his father’s law firm. He was drawn to understanding and implementing technology to help attorneys adapt to the rapid infusion of data brought by the digital age and the impact that had on the discovery process and juror expectations. With his creative visual solutions and legal background, Pete established a reputable business, spending years assisting trial attorneys in developing strategies and presenting evidence. In 2007, Pete started Precise’s eDiscovery and Forensics division to provide sound resources to attorneys navigating the influx of electronically stored information (ESI), directly managing hundreds of eDiscovery projects. In 2016, he instituted Precise’s Advisory division, offering attorneys structured and statistical approaches to determine key elements in their litigation, including case valuation, probability of award, juror bias, critical concepts, and ideal juror selection. Pete’s multifaceted litigation-strategy expertise allows him to bring a unique holistic perspective to his work.
Under Pete’s leadership, Precise’s e-discovery and digital forensics team has engaged in matters involving collection, analysis, searching, processing, production, and expert testimony in a broad array of cases nationwide over 15 years. He frequently shares his e-discovery and forensics expertise during seminars and CLEs.
Pete attended Washington and Jefferson College and earned his JD from Duquesne University School of Law. Pete enjoys spending time with his family, traveling, woodworking, and entertaining during his free time. Known for his sense of humor (at least in his mind), you will likely find a smile on his face.
