Mrs. Hart's journey into supplier diversity began unexpectedly after she first pursued a career in engineering change management.

She accepted training to become a subject matter expert, which proved transformative and set the course for her professional trajectory. Having served in the field for more than two decades to date, she has continually advanced through leadership roles, taking pride in the relationships she has built and the impact she has made by championing underrepresented suppliers.

Prior to beginning her tenure at Tenneco, Mrs. Hart served as a program management system coordinator, engineering change management at Faurecia Interior Systems from 2012 to 2013, during which she managed engineering modifications and facilitated communication between departments to ensure the seamless implementation of changes.
