Judge Tammy O'Brien: Professional Background and Legal Expertise

Appointed By: Gov. John R. Kasich, Jr.

Biography

The Hon. Tammy O'Brien is a judge for the General Division of the Summit County Court of Common Pleas in Ohio. She was appointed to the bench by former Governor John Kasich on April 11, 2011, filling a vacancy created by the retirement of the Hon. Brenda Burnham Unruh (deceased).

O’Brien has presided over the Summit County Reentry Court since 2016. The court is designed to help citizens successfully reenter society following incarceration.

Prior to her election, O’Brien was an attorney at Roderick, Linton, Belfance (1999 to 2011) and Scanlon & Gearinger Co. (1994 to 1998). She handled business and general civil litigation as well as tort and employment litigation.

O'Brien earned a bachelor’s degree in secondary education from the University of Akron in 1988. She then completed a J.D. at Cleveland-Marshall College of Law in 1992. She has been admitted to practice law in Ohio, the United States District Court for the Northern District of Ohio, and the Sixth Circuit Court of Appeals.

After graduating from law school, O’Brien began her legal career as a judicial law clerk for the Hon. William R. Baird of the Ohio Ninth District Court of Appeals. She served in that capacity until 1994, at which time she entered into private practice.

Her memberships have included the Ohio State Bar Association, the Akron Bar Association, and the Ohio Women’s Bar Association. She also sat on the Ohio State Board of Education, the Board of Trustees of the Summit County Chapter of the American Red Cross, and the Board of Trustees of H.M. Housing, Inc.’s Multi-State Low Income Housing Program.

She is a co-author of a legal treatise involving the introduction of evidence at trial. The piece, entitled Ohio Motions in Limine: Evidence Exclusion Guide, has been published by Thompson West since 2007.
