Courtney Mendelsohn represents a diverse corporate client base in complex commercial litigation and product liability matters in federal and state courts across the United States.

Courtney particularly enjoys defending clients in class actions and multidistrict litigation (MDL) and has focused her practice in these procedural areas. She appreciates the magnitude of issues inherent in class action and MDL work and ensures she incorporates clients’ goals throughout each stage of the litigation.

Courtney regularly performs tasks across the gamut in single-case and class-action litigation, including initial case assessment and strategy; drafting pleadings, trial court briefs, and appellate briefs; managing discovery, including e-discovery; executing efficient and thorough research; taking and defending depositions; working with experts; making court appearances and arguments; and handling mediations. Throughout the course of her career, she has amassed broad experience across substantive areas including antitrust claims, business torts, consumer fraud actions, consumer protection cases, contract disputes, and credit reporting disputes, among others.

Courtney's active pro bono practice includes representing clients at the appellate level in habeas corpus proceedings and immigration cases.

Away from her law practice, she enjoys skiing, researching and exploring residential real estate markets, and watching college football.
