Tina Grandinetti proudly represents District 20, Kapahulu, Kaimukī, Waialae-Kahala, and Diamond Head, in the Hawaiʻi State House of Representatives.

​

Born and raised on Oʻahu, she is driven by a deep love for the lands, waters, and people of Hawaiʻi — and a grounding belief in politics that put people before profit. Before joining the legislature, Tina worked as a housing policy researcher, legislative staffer, educator, and community organizer. She earned her Bachelor's and Master's Degrees in Political Science at the University of Hawaiʻi at Mānoa and her Ph.D. from RMIT University's Center for Urban Research in Australia, where her research focused on Hawaiʻi's housing crisis. Interviewing working families and people experiencing homelessness on Oʻahu taught her that real solutions come when we listen to and empower the people most impacted.

​

Tina also worked as an activist and organizer, and she brings that same passion with her to the legislature. She mobilized young people in the island-wide effort to protect Oʻahu's aquifer following the Red Hill fuel leaks, and served as Vice President of Hawaiʻi Peace and Justice. She was also a member of the Honolulu Tenants Union and Hui Aloha ʻĀina o Honolulu, and taught political science at UH Mānoa, the University of Melbourne, and Roosevelt High School.

​

Now, as representative, Tina serves as Vice Chair of the Committee on Consumer Protection and Commerce. Families across Hawaiʻi are being squeezed by rising costs — from rent and groceries to insurance and healthcare. As Vice Chair, her focus is to increase competition, rein in corporate abuse, and ensure that laws prioritize affordability and protect consumers' dignity.

​

Tina also co-chairs the Working Families Legislative Caucus, where she works closely with community advocates to build power for working families, advance tax fairness, and advocate for the public services that help people live and thrive in Hawaiʻi.
