About Sergei
An economics major who moved into law, Sergei Lemberg combines numerical training and legal education in a practice that spans state and federal courts. He earned his J.D. from the University of Pennsylvania Law School in 2001 after completing a B.A. in economics, with a minor in business, at Brandeis University in 1997. The academic record shows a steady progression from economic study to legal work, and a timeline that places him in practice through the early 2000s and beyond.
After law school, Lemberg entered private practice and within a few years assumed a leadership role at Lemberg Law. He has served as Principal at the firm since 2006. That title indicates a central management and supervisory role. Over the years he has overseen litigation strategies, case filings and court appearances in multiple jurisdictions.
His admissions list reflects work across a broad geographic and procedural range. He is admitted in Florida, Pennsylvania, Massachusetts, Georgia, Connecticut and New York. He also holds admissions to practice in several federal appellate circuits, including the 1st, 2nd, 3rd, 5th, 9th and 11th Circuits. Those credentials allow him to handle matters at both trial and appellate levels and to file appeals across regional federal panels.
Colleagues and court records show a practice that frequently crosses state lines. Managing a caseload that spans several states and federal circuits requires attention to differing procedural rules and deadlines. His firm’s docket reflects steady activity in federal courts and state courts in the jurisdictions where he is admitted.
Lemberg’s background in economics appears to inform how he approaches evidence and damages issues. He has experience preparing court filings, arguing motions and participating in appellate briefing in multiple circuits. He balances court work with the administrative duties that come with running a law office, including managing staff and coordinating litigation across forums.
Those who work with him describe a lawyer who combines legal training with practical courtroom experience.
