About Karen L.
Karen L. Hagberg built her legal foundation at Cornell Law School, where she earned her J.D. in 1984. Before that, she completed a Bachelor of Arts at Binghamton University in 1977. Those years of study set the stage for a long career in the New York legal community. The classroom work, the classmates and the early internships shaped how she approached legal problems. They also placed her on a steady path toward practice in the state.
After law school Hagberg entered private practice and established herself in New York. She is admitted to the State Bar of New York. Over the decades that followed she moved through roles of increasing responsibility and experience. Her progression mirrors the arc of many lawyers who enter large firm practice and remain there, taking on heavier matters as their careers advance. Colleagues describe her as steady and methodical in the way she handles files and clients.
A significant portion of Hagberg’s career has been at Morrison & Foerster LLP, where she became a partner. At the firm she has worked alongside teams on matters that require coordination across practice groups. Days in that environment are often busy and varied. Partners at large firms juggle client work, internal management and mentoring junior lawyers. Hagberg’s record shows she has been part of that day-to-day mix for many years.
Her legal experience spans a long calendar. Since receiving her J.D. in 1984 she has practiced through multiple legal market cycles. That longevity brings perspective about how firms operate and how clients change over time. It also means she knows the institutional rhythms of a large national and international firm. She has seen issues move from local to national importance and has adapted to new procedural and regulatory developments as they arrived.
Outside the specifics of any single case, Hagberg’s career reflects continuity. She has held a partner position and remained active in the firm environment. Her work requires negotiation, drafting and the kind of problem solving that clients expect from senior counsel. Her colleagues rely on her judgment when matters require calm assessment.
As of 2026 Karen L. Hagberg is a partner at Morrison & Foerster LLP and continues to practice law in New York, handling matters for the firm’s clients in that jurisdiction.
