About Mario J
Mario J Fiumefreddo completed his legal training at Marquette University Law School, earning his J.D. in 2021 after beginning studies in 2018. He came through a law program known for blending classroom work and clinic experience. Those formative years shaped how he approaches written advocacy and client counseling.
After law school he entered the Wisconsin bar and established his practice in the state. He holds current membership in professional associations and participates in local legal circles. That involvement keeps him connected to changes in state rules and practice trends.
Fiumefreddo’s early professional years have been spent at Van Severen Law Office, S.C., where he joined colleagues handling day-to-day matters for individuals and businesses. His work has involved advising clients, preparing filings, and managing case workflows. He balances office responsibilities with appearances when matters require it, handling tasks that range from client intake to negotiating resolutions.
Colleagues describe him as pragmatic in his approach to problems. He tends to break complex issues into manageable parts and sets practical goals for each stage of a matter. He writes clearly and aims to give clients straightforward explanations of options and likely outcomes. Those traits inform how he builds cases and communicates in and out of court.
Fiumefreddo practices primarily in Wisconsin courts and administrative forums. He keeps his practice local, focusing on the needs of clients in the communities he serves. That local orientation also shapes how he evaluates remedies and timelines for cases.
Outside the office he maintains ties to his law school network and to peers across the state. He follows developments in Wisconsin law that affect everyday practice and adjusts his approach as those developments unfold. The combination of recent legal education and active practice gives him a perspective that bridges current case law and practical client service.
He is currently an attorney at Van Severen Law Office, S.C., where his practice focuses on serving clients across Wisconsin.
