Our team differentiates ourselves in our commitment to question assumptions, be the independent eye, critically analyze facts and tell our clients what they need to know to make sound decisions. Duff & Phelps cuts through complexity and creates clarity for our clients to ensure compliance, reduce risk, overcome emerging challenges and enhance value.

William Duff and George Phelps founded Duff & Phelps in 1932 in Chicago because they saw that banks and insurance companies struggling in the Great Depression needed investment research based on rigorous analysis and technical expertise. 

Over the years, the firm branched into financial advisory and corporate finance, broadening and deepening our service offering and expertise to assist businesses in industries outside of the banking and insurance sector while maintaining the same commitment to technical expertise. Through acquisition and organic growth Duff & Phelps has developed into the diverse and agile firm it is today, serving more than 5,000 clients each year, including over 50% of the S&P 500, 60% of the Fortune 100, 80% of the Am Law 100 and 70% of the world’s top-tier hedge and private equity funds.
