Prior to joining Kabateck LLP, Ms. Mazzella spent five years as a litigator at a civil defense firm where she focused on motion and appellate work. As a defense litigator, Ms. Mazzella researched, drafted and successfully argued over one hundred motions and briefs, in both state and federal courts, in a variety of areas, including products liability, employment, business litigation, professional liability and consumer protection laws. Ms. Mazzella served as a judicial extern for the Honorable S. James Otero of the United States District Court during law school and as Editor in Chief of the Loyola Law Review.

Ms. Mazzella most recently helped secure a confidential six-figure settlement from Clayton Valley Charter High School on behalf of a female student who was sexually assaulted by a male student on the school’s campus. In addition, she has also helped secure a $1,350,000 settlement on behalf of a young mother who was catastrophically injured after her car was hit by Riverside Transit bus. In a case involving catastrophic injuries, Anastasia reached a $925,000 settlement on behalf of her client who was injured after an employee of Hylkema Roofing Company struck her vehicle.

In cases involving school sexual assaults, Anastasia represented a female student who was assaulted by a male student at the Animo Venice Charter High School campus. She also represented a student  who was sexually abused as a minor by a teaching assistant against Fresno Unified School District. In both cases, Anastasia secured a confidential six-figure settlement. 

In a case involving partnership liability disputes, Anastasia secured a $750,000 settlement on behalf of a bankruptcy debtor seeking contribution from OOCL and OOCL Logistics on a partnership liability theory. 

Ms. Mazzella has also obtained a $2.1 million settlement in a medical malpractice case involving a premature infant who was born at 28 weeks gestational age. Days after being discharged from the NICU in good health, he was brought back to the hospital in distress and assessed by a pediatric ER physician who later sent him home, attributing his symptoms to colic. The next day the plaintiff went into cardiac arrest and was airlifted to the hospital where he was diagnosed with late-onset group B streptococcal infection and Hypoxic Ischemic Encephalopathy. It was undisputed that the child had severe brain damage, would never be able to work or engage in any meaningful conversation, and would require supervision for the rest of his life.

Ms. Mazzella currently sits on the Board of Governors of the Association of Business Trial Lawyers (ABTL).

Ms. Mazzella is licensed to practice in California as well as all districts of the United States District Court in California.
