NISA's founders, Jess Yawitz and Bill Marshall, began their careers as professors at Washington University in St. Louis, where they were early pioneers in research on fixed income investing and the concepts of interest rate risk management and immunization. After leaving academia to work on Wall Street, Jess and Bill returned to St. Louis, founding NISA Investment Advisors, LLC in 1994 as a firm focused on fixed income investing for large institutional investors.
