Tammi Hart is Helping Make Diversity a Deeply Held Value at Tenneco


Tammi Hart is Director of Purchasing, Supplier Diversity, and Corporate Services for Tenneco. She holds an MBA from Davenport University, as well as a certificate in Supplier Diversity Professional Excellence from the Tuck School of Business. One of her proudest accomplishments so far at Tenneco is working to truly integrate diversity as a value into the corporate mindset of Tenneco’s leadership. She finally felt she had accomplished this goal this year, when supplier diversity occupied a full-page section in the company’s annual Global ESG Sustainability Report. Hart focuses on the use of internal platforms, such as the company’s intranet and the Black African Heritage Business Resource Group, to help educate the Enterprise on the value of diversity from a variety of metrics.


She is also deeply committed to increasing organizational connections with diverse suppliers by bringing them into contact with top decision makers through a Diverse Supplier Spotlight Series, managing an interactive directory, and facilitating one on one meetings. This community emphasis has won Hart a number of awards and nominations, including those from the Great Lakes Women’s Business Council, the Asian Pacific American Chamber of Commerce, and more.
