As a mother, state representative and former city council member, Tana brings a unique perspective to legislative issues. She has consistently advocated for improving life and work balance for busy families, addressing ongoing education and transportation investments and using taxpayer dollars judiciously.

In the Legislature, Tana has championed legislation to close the gender pay gap and ensure our children have the interpersonal skills needed to succeed by expanding social emotional learning in our schools.

Prior to her tenure on the Mercer Island City Council, Tana worked as Communications and Marketing Director for the Jewish Federation of Greater Seattle, which raises money to help the elderly, refugees and families in need both locally and abroad.

After earning a Master’s Degree in Public Policy and Administration from Columbia University, Tana worked as the national director of domestic policy at the Jewish women’s organization, Hadassah. She continued her work with nonprofits as a government relations and communications consultant for the next decade.

Tana has volunteered in her community in numerous capacities including on the boards of the Mercer Island Youth & Family Services Foundation, the Island Park Elementary School PTA, the Jewish Federation of Greater Seattle and the National Breast Cancer Coalition.

As a state representative for the 41st Legislative District, Tana sits on the Appropriations Committee, the Education Committee, and the Early Learning and Human Services Committee, where she serves as Vice Chair. She previously served as Vice Chair of the Environment Committee as well. Additionally, Tana represents the House Democrats as their legislative liaison to the State Building Code Council.

Tana and her husband have two young children and a big black lab.
