Beginning her career at Alcoa, Rebecca developed a foundational expertise in accounting, cost management, and internal audit—disciplines that would shape her trajectory for decades to come.

She led teams through audits, system transitions, process redesigns, and large-scale operational shifts with a focus on building systems that were not only compliant, but sustainable. Her leadership blended analytical skill with a deep respect for people, allowing her to strengthen processes without disrupting the human foundation that drives operational performance.

As Director of Internal Control for the Engineered Products and Solutions business group, she managed risk and compliance frameworks spanning financial systems, environmental health and safety, information technology, import/export protocols, and anti-corruption readiness.

She established controls, trained leaders, and strengthened risk management practices that enhanced both accountability and performance. Her influence extended beyond procedures, shaping cultures of compliance and operational discipline in regions with varied regulatory expectations and operational challenges.
Rebecca’s impact deepened further during her consulting engagements with Howmet Aerospace, where she supported multiple locations through controller transitions, internal audit preparation, and inventory assessments.

Whether eliminating aged material, coaching financial analysts, or restoring stability during periods of turnover, Rebecca consistently delivered grounded guidance that improved financial accuracy and operational alignment.
Across her global career, Rebecca has gained extensive international exposure in regions including Germany, France, United Kingdom, Netherlands, Morocco, Canada, Mexico, Australia and Brazil. These experiences have shaped her into a leader who understands not only the technical dimensions of global compliance, but the cultural intelligence needed to build trust across diverse teams. Her collaborative and respectful approach has allowed her to mentor leaders worldwide and influence organizational practices that reflect both global standards and local realities.
At the heart of Rebecca’s leadership is her steadfast commitment to ethical conduct and personal responsibility. Her teams have long recognized her as a mentor who leads by example, prioritizing transparency, fairness, and thoughtful decision-making. Her values serve as a stabilizing force during complex or uncertain moments, and she is frequently relied upon to navigate challenges that require both technical understanding and moral clarity.
