Download Bio

Ms. Liu graduated from the University of Texas at Dallas with a Bachelor of Science degree in Molecular Cell Biology, but science was not her life’s calling. Instead, she enrolled in St. Mary’s University School of Law, where she served as a Staff Writer on the school’s law review, was recognized for academic achievement by listing on the Dean’s List and won the Ladas Memorial Award for Writing Excellence. During law school, she clerked for the Fifth District Court of Appeals in Dallas.

A published author, Ms. Liu has 16 years of extensive trial experience in family law litigation, particularly in the areas of child support litigation and family immigration issues. Born in Taiwan, Ms. Liu has a unique perspective due to her immigrant background and her previous experiences as an Assistant Attorney General for the State of Texas and as a managing attorney for a non-profit organization helping victims of family violence and human trafficking.

A native speaker of Mandarin Chinese with proficiency in Cantonese and French, Ms. Liu is married and has two children, one dog, one cat, and two pet lizards.
