She excels at identifying the decisive facts and issues that shift cases in her clients’ favor. Clients value her clear communication, efficiency, and ability to minimize business disruption while driving toward the outcome that matters most to them, whether that is a strategic settlement or a trial win.

Her experience spans computer hardware and software, telecommunications, video streaming, medical devices, consumer products, pharmaceuticals, biologics, and emerging technologies.
