Aaron is a native of the St. Louis Metro area, and grew up in Florissant, Missouri. He was raised in a working class family who faced their share of struggles, which came to a head when his father lost most of his vision and became disabled. Watching his father's life savings and livelihood slip away after a lifetime of hard work motivated Aaron to work hard in school, so he could help other people avoid the same fate or worse.
He received his bachelor's degree in History from Saint Louis University, graduating summa cum laude in 2009. He then received his juris doctorate from Saint Louis University in 2012. While he was in law school, Aaron clerked for the firm, where he got his first taste of the rewards that come from representing injured people.
Before joining the firm, Aaron worked at private firms in Edwardsville and Belleville, where he focused on defending local businesses and municipalities throughout Southern Illinois, including police and fire departments, school districts, and other local governmental entities.
