About Dan P.
Dan P. Sedor built a legal career that moves between state courts and the federal bench. He arrived in law after earning a B.A. from the University of California, Los Angeles in 1982 and then completing a J.D. at Loyola Law School, Los Angeles in 1988. Those academic years set the stage for work in litigation at both associate and partner levels.
Fresh out of law school in 1988, Sedor joined Sidley Austin as a litigation associate. The position placed him in a national firm environment early in his career. Four years later he took a partnership role at Jeffer Mangels Butler & Mitchell LLP, becoming partner in 1992. That move anchored him in a California-based practice and in private firm leadership.
His bar membership is current with the California State Bar. He is admitted to practice in California and before several federal forums. Those include the Ninth Circuit and the U.S. District Courts for the Central, Northern, Southern and Eastern Districts of California. The range of admissions reflects sustained work in both trial and appellate venues.
Sedor’s career shows steady progression from associate to partner. Early litigation training at a national firm fed into years at a regional firm where he has handled matters that required appearances across multiple districts. He has managed litigation that uses both state procedural tools and federal rules. He has experience preparing filings for trial courts and for appellate review in the Ninth Circuit.
Colleagues and records describe him as the type of lawyer who balances courtroom work with firm responsibilities. His time at Jeffer Mangels Butler & Mitchell LLP spans decades and includes supervising teams of lawyers on complex matters. The office setting has kept him engaged in California’s commercial and civil dockets, as well as in federal court practice where multi-district or cross-district issues sometimes arise.
Outside of court appearances, Sedor’s background reflects a conventional path through law school clerkships, private firm associate work and then partnership. That sequence is familiar, but it also denotes long-term involvement in litigation practice across state and federal systems.
He currently practices at Jeffer Mangels Butler & Mitchell LLP and handles matters in both California state courts and federal courts, including the Ninth Circuit and U.S. District Courts in the Central, Northern, Southern and Eastern Districts of California.
