About

Originally from rural west St. Louis County, Andy moved to Columbia in 1991 to attend the University of Missouri like his parents and grandparents before him. He earned two bachelor’s degrees with honors in English and psychology in 1995, and a master’s in English in 1999.  After graduate school, Andy stayed at Mizzou to teach freshman composition and world literature full-time for another three years.

In 2002, Andy left the English Department to go to law school. He won a spot on Mizzou’s national moot court team, founded the student chapter of the American Constitution Society, and served as editor-in-chief of the Missouri Law Review. Graduating cum laude in 2005, Andy was awarded the Judge Shepard Barclay Prize, which goes to the graduating law student “who has attained the highest standing in scholarship and moral leadership.”

After law school, Andy clerked for U.S. District Judge Nanette K. Laughrey for two years before entering private practice as an associate at Jenner & Block LLP in Chicago. Among other clients, he represented a national trucking company in an EEOC enforcement action, defended a media company from defamation claims, and sought a new trial for a death-row inmate.

In 2010, Andy came home to Missouri to work for Attorney General Chris Koster. Promoted to Deputy General Counsel in his second year at the AG's Office, Andy handled some of the state's highest profile cases. He defended Missouri statutes from constitutional challenge, sued municipalities in St. Louis County for collecting excessive traffic fines, and represented Missouri in a massive arbitration between 46 states and the largest cigarette manufacturers in the country.  Andy’s successful appeal of the arbitrators’ ruling to the Missouri Supreme Court recovered more than $50 million in tobacco settlement proceeds for Missouri taxpayers. He also served as Koster’s official speech writer and taught constitutional law at the University of Missouri.

Andy left state government on Koster’s last day as attorney general. On January 10, 2017, he joined his former colleagues Joanna Trachtenberg and Julianne O’Bannon Germinder to form TGH Litigation LLC, an employment discrimination and civil rights law firm in Columbia. Building on the work he did at the AG’s Office, Andy’s practice focuses primarily on state and federal constitutional law.

Andy lives in southern Boone County with his wife, Kerry Mulvania Hirth, a working artist who also teaches ethics at Moberly Area Community College.
