About Mark
Mark Tassone practices law in Ohio and in federal court for the Southern District of Ohio. He is admitted to the Ohio bar and authorized to appear before the United States District Court for the Southern District of Ohio. His practice bridges state and federal matters and centers on representation in court proceedings and pretrial work.
Tassone's path to the courtroom has been practical rather than theatrical. He operates out of Thomas Law Offices, PLLC, where he handles filings, motions and hearings on behalf of clients. He prepares cases for trial when necessary and works through negotiations and settlement discussions when that delivers the best result for a client. He is comfortable in both the paperwork of litigation and the pressures of a hearing calendar.
Colleagues describe his style as straightforward. He favors clear briefs and direct oral advocacy. He approaches each file by identifying the immediate procedural steps and the longer-term objectives. That approach informs whether a matter is steered toward early resolution or carried forward to trial. He also spends time counseling clients about expectations in state and federal court, helping them understand the differences in procedure and scheduling.
Tassone appears regularly in court in Ohio and in the Southern District of Ohio. He files pleadings, argues motions and represents clients at status conferences. He has experience working within the federal court’s local rules and scheduling orders, including handling the discovery rhythms federal practice demands. In state court matters, he adapts to local practices and dockets across Ohio jurisdictions.
At Thomas Law Offices, PLLC, Tassone contributes to the firm’s litigation practice. He collaborates with colleagues on strategy and shares responsibility for case management. He also interacts with opposing counsel and court staff, maintaining the practical communications that keep cases moving.
Outside of hearings and filings, he places emphasis on case preparation. That includes document review, deposition planning and crafting written arguments. He tends to take a methodical approach: gather the facts, map the legal issues, and set a timeline that matches court-imposed deadlines.
As of 2026, Tassone continues to practice through Thomas Law Offices, PLLC, representing clients in Ohio courts and in the United States District Court for the Southern District of Ohio.
