About Robert Aaron
Robert Aaron Miller built his path to law after an earlier interest in education. He earned a B.S. in Elementary Education from Kentucky Christian University in 1986 and followed that with a J.D. from Capital University Law School in 1989. Those classroom years set a foundation for courtroom work that would come quickly thereafter.
Miller moved into public service at the start of his legal career. In 1990 he served as an Assistant Prosecuting Lawyer in Muskingum County. The role put him in front of juries and judges and gave him hands-on experience handling criminal matters and working with law enforcement. It was practical training in trial work, evidence and courtroom procedure.
His admissions reflect a practice that spans state and federal arenas. He is admitted to practice in Ohio, before the Sixth Circuit, and before the U.S. Supreme Court. Those credentials allow him to take cases through state trial courts, into federal appeals, and, where appropriate, to the nation's highest court. Such a range can be useful for clients who need representation across multiple forums.
After his time in the prosecutor’s office, Miller established a private practice. He opened the Miller Law Office and has maintained that practice since then. The office handles matters that arise in the jurisdictions where he is licensed. Miller’s background in prosecution informs how he approaches litigation, evidence and case strategy. He brings courtroom experience to representation on both sides of the aisle.
Colleagues describe him as steady in court and plainspoken in the office. He tends to take cases that require trial experience and an understanding of appellate procedure. Over the years he has developed a practice that balances courtroom work with the procedural demands of appeals when a case requires it. He also draws on his early training in education when explaining complex legal points to clients and juries.
Now practicing in 2026, Miller remains based at the Miller Law Office. He handles matters in Ohio and in the federal courts where he is admitted, including the Sixth Circuit and the U.S. Supreme Court, and continues to accept cases that require trial and appellate advocacy.
