After earning her bachelor's degree from the University of Texas at Austin and her law degree from St. Mary's University School of Law, Senator LaMantia returned to the Rio Grande Valley, where she worked as an associate attorney at Atlas, Hall & Rodriguez, LLP. She soon went on to work in data analytics for her family business, L&F Distributors, where she currently serves as In-House Counsel. Her achievements at L&F include revamping the company's healthcare plan for over 1,200 employees and promptly resolving supply chain and safety equipment issues that resulted from the COVID-19 pandemic.

As an active member of her community, Senator LaMantia has served on the boards of the Stars Scholarship Fund, the Gladys Porter Zoo, and the Museum of South Texas History. By building opportunities through hard work, giving back, and paying it forward, she seeks to carry on the legacy of her grandfather, Joe LaMantia Jr., who inspired her journey in public service.

Senator LaMantia is a member of the distinguished Senate Committees on Education, Health & Human Services, Nominations, and State Affairs, which headline debate on the legislature's most contentious topics and impactful issues. In her first term as a Senator, she used her position to expand opportunities for the Texas workforce, increase access to affordable healthcare, support public school students and teachers, deliver funding for rural areas, and much more.

Her advocacy and accomplishments have earned Senator LaMantia numerous awards that coincide with her principles centered around hard work, trustworthiness, and collaboration. She attributes the successes of her first session to her South Texas upbringing, real-life work experience, and the dedication of her esteemed colleagues, fantastic team, and valued community leaders.
