About James G.
James G. Onder earned his law degree from Saint Louis University School of Law, with his J.D. conferred in 1988. He entered the profession at a time of shifting litigation practice and has built a career that spans both sides of the Mississippi. He is admitted to practice in Illinois and Missouri and has woven those jurisdictions into the framework of his work.
His early years in practice are not laid out here in full detail. What is clear is a steady move into leadership. He now serves as CEO of OnderLaw, LLC. In that role he manages the firm’s operations and plays a prominent part in case direction. He has navigated the administrative responsibilities that come with running a multi-jurisdictional practice while also remaining involved in client matters.
Colleagues and court records note a trial-oriented approach in service of clients’ interests. He has handled litigation that required courtroom advocacy, case development, and strategic planning. The work demands attention to evidence, witness preparation, and the rhythms of trial calendars. Those elements have shaped how he structures teams and prepares cases at OnderLaw.
Over the years he has balanced managerial duties and courtroom work. Leading a firm requires decisions about staffing, case selection, and litigation strategy. He has overseen those decisions and maintained an active presence in significant cases. That combination of leadership and practice gives him a broad view of how litigation functions from intake through resolution.
Community and professional engagement often accompany a career like his, and his practice reflects ties to both Illinois and Missouri legal communities. He has built relationships across state lines and maintained the licensure necessary to represent clients in both forums. That dual-admission informs how his office approaches filings, trial preparation, and client counseling when issues cross jurisdictions.
Today he leads OnderLaw, LLC as its CEO and continues to represent clients under the firm banner. His current practice focuses on matters arising in Illinois and Missouri through OnderLaw, LLC.
