Jessie was born in El Salvador and moved to the United States with her family in 1984 in the midst of a civil war. Coming to America provided many opportunities for Jessie and her family. Hard work and dedication to education was the key to capitalizing on those opportunities.

Jessie graduated from Hamilton High after three years, and enrolled at Marquette University on an academic scholarship. She received a B.A. from Marquette in Spanish and Communications Studies, which she put to use as an outreach coordinator for Hispanics for School Choice – a nonprofit organization that helps low-income parents find schools for their children.

Since 2013, Jessie has served Oak Creek, South Milwaukee, and parts of Franklin in the Wisconsin State Assembly. The new 21st Assembly District will include all of Oak Creek, and parts of Greenfield and Milwaukee.

Jessie served on Assembly leadership as caucus secretary for six years, and now she sits on the Joint Committee on Finance, which crafts the state's biennial budget. During her time in office, Jessie has passed billions in tax relief to benefit the middle class, retirees, and families. This session, she co-authored 2023 Wisconsin Act 12, which reformed shared revenue in Wisconsin and provided additional support to police, fire, and EMS services.

Jessie, her husband Aaron, and their son Noah make their home in Oak Creek.
