Our Story

After years of practicing in large firms, corporate legal departments, and even federal investigative agencies, we saw a gap in the legal market: high-level legal expertise delivered with personal attention. Mulhall Zion LLC was formed when two experienced attorneys combined their practices to give clients the best of both worlds—big-firm skill with small-firm accessibility.


We’ve chosen to stay lean, so we can stay close to the work and our clients. That means no unnecessary bureaucracy, no nickel-and-diming for every minute, and no disappearing once the ink is dry.

Connected With Leaders in Law & Business

Our work doesn’t end when the office lights turn off. The attorneys at Mulhall Zion LLC are active participants in the communities we serve, staying connected through professional associations, alumni networks, veterans’ organizations, and local cultural groups.


These connections keep us grounded in the values we share with our clients—hard work, service, and a commitment to helping others succeed. From leadership roles in local bar associations to involvement in business and civic groups, we invest our time and energy in organizations that strengthen Northeast Ohio.
