Executive Overview

I am a cybersecurity leader with extensive experience overseeing cybersecurity and information risk management programs at financial services and insurance organizations. I have led the transformation and implementation of cybersecurity tools and processes enabling cyber resilience and agility at several Fortune 500 companies. Aside from the day-to-day responsibilities of my role, I am a fierce advocate and strategist for increasing diversity in the technology industry and addressing the cybersecurity workforce shortage through my involvement in organizations including the Executive Women’s Forum, ISACA One in Tech, and the FS-ISAC.
