Tricia Griffith was named the CEO of Progressive Insurance in July of 2016. Her journey at Progressive began in 1988, when she joined the company as an entry-level claims representative. Since then, Tricia has held several leadership positions, including Chief Human Resources Officer, President of Claims, President of Customer Operations and Personal Lines Chief Operating Officer.

During her tenure as CEO, Tricia has led the company to historic growth, earning her Fortune Magazine’s 2018 Businessperson of the Year. Much of that growth is the result of her strategic approach to increase the company’s book of business among a preferred segment of customers who bundle home and auto insurance. Under her leadership, Progressive customers in that segment have grown from 400,000 to more than 1 million. She’s leading Progressive through that pursuit while continuing to grow the company’s traditional auto business, as Progressive moved from fourth to third on the list of US auto insurers, based on written premium, in 2018.

While her business acumen has driven results, it’s her approachable and authentic leadership style that many employees will cite as a key to the company’s success. Tricia puts a premium on creating a diverse and inclusive environment for all employees and speaks frequently about the importance of bringing your whole self to work. The efforts have paid off. In 2018, Progressive’s annual Culture Survey placed the company in the 96th percentile of all companies who use Gallup’s survey, showing an engaged culture that’s leading to success. Additionally, under Tricia’s leadership, Progressive achieved the #1 ranking in The Wall Street Journal’s first corporate ranking of diversity and inclusion in 2019, and in 2021, the National Association of Corporate Directors recognized the Progressive board with their Diversity, Equity, and Inclusion award.

Tricia has a bachelor’s degree from Illinois State University and is a graduate of the Wharton School of Business’ Advanced Management Program. In addition to sitting on the board of the Business Roundtable, she serves on the Board of Directors for FedEx, and is an associate of the Business Council.
