Adrienne Tregnago Spiller HeadshotAttorney

Ms. Spiller grew up in Randolph County, Missouri and attended Moberly High School. She obtained her Bachelor of Science in Juvenile Justice and Associate of Science in Law Enforcement from Missouri Southern State University in 2009, graduating with honors.

Adrienne received her law degree from the University of Missouri – Columbia School of Law in May 2016. During law school, she published an article with proposed legislation for the State of Missouri to stop the shackling of pregnant inmates, and testified before a Senate Committee in an attempt to get the bill through Congress. Ultimately, in 2018, Missouri rightly enacted an anti-shackling law.

Prior to joining Gump & Faiella, LLC, Adrienne practiced as an Assistant Prosecuting Attorney for Randolph County, Missouri, then as a Family Law and Adoption Attorney for Columbia Family Law Group in Columbia, Missouri.
