Cassandra C. Thorson

The firm is led by its founder, Cassandra Thorson, who graduated with honors from Southwestern University School of Law, Los Angeles, California. She went on to receive, with honors, a Master’s Degree in International and Comparative Law from Georgetown University School of Law, Washington D.C.

Cassandra’s mother immigrated from Singapore when she married Cassandra’s father and moved to a small town in Kansas. Due to a lack of a consulate in the small town, her mother had to wait until she moved to San Diego to complete the citizenship naturalization process, but Cassandra recalls her mother becoming a citizen as a highlight of her high-school years.

These experiences have helped shape her views on who needs the most help and how she can provide it. A career dedicated to helping those suffering from traumatic brain injuries, Attorney Cassandra Thorson is empathetic to the needs of her clients. She is a fierce trial attorney who fights with her years of experience, knowledge, and charisma. She is a woman of integrity, intelligent, fair, a fighter, a defender of human rights, who seeks, above all things, the well-being of those she has represented.

Her hobbies include teaching Yoga at the beach.
