About Leslie C.
Leslie C. Leone is an attorney admitted to practice in California and the Federal Circuit. She has combined courtroom work, union-side practice and mediation work over a career that spans more than two decades.
She earned a J.D. from Golden Gate University School of Law in 1998. Earlier she completed a B.A. in English at the University of California, Berkeley in 1987. Her academic background also includes study at Boston University in 1983.
Early in her legal career she served as a staff lawyer and business agent for Teamsters Union Local 856 in 1999. That role placed her at the intersection of labor representation and everyday legal problems confronting union members. The experience informed how she approaches client work, blending practical problem solving with formal advocacy.
Leone holds a Mediation Certificate from Community Boards San Francisco. She was listed as a mediator with the Office of Citizen Complaints from 2010 to 2014, handling matters brought to that city oversight body. Those years added formal alternative dispute resolution experience to her portfolio and gave her regular exposure to administrative processes.
She has been a member of the California Bar since 1999 and maintains membership in the San Francisco Bar Association. Admitted to practice before the Federal Circuit as well as in California courts, she moves between state and federal dockets when necessary. Her record reflects work on employment and labor-related matters, public-facing administrative cases and private disputes that can benefit from mediation.
Leone practices under the name Leone Law Office. She has operated as a lawyer there while also engaging in other legal and community roles. Colleagues describe her approach as pragmatic: she prepares for trial when it is necessary and looks for negotiated paths when they are appropriate.
Her practice combines litigation and dispute resolution. She represents clients in California courts and appears before the Federal Circuit when appeals or specialized federal matters arise. She currently practices at Leone Law Office, representing clients in California and before the Federal Circuit and handling litigation and mediation matters.
