Business visionary Rodger Riney and his wife, Paula Riney, have for decades uplifted the St. Louis community through a variety of philanthropic endeavors. Rodger Riney earned a bachelor’s degree in civil engineering and a master’s in business administration in 1969 from the University of Missouri–Columbia and then joined Edward D. Jones & Co., eventually becoming a partner. In 1980, he decided to become part of a new industry called discount brokerage, starting his own firm, Scottsdale Securities.
By the 1990s the business was predominantly online, and its name changed to Scottrade Inc. But its core business model of low commissions, no investment advice, branch offices to help clients and award-winning customer service remained. The firm was included six times on Fortune magazine’s “100 Best Companies to Work For” and won 11 JD Power awards for Best Discount Brokerage. The firm eventually opened 500 branch offices in 48 states. After a diagnosis of multiple myeloma, for which there was no known cure, Riney decided to sell Scottrade to TD Ameritrade in 2016.
Both the Rineys had parents who suffered from neurodegenerative diseases. This led to their early philanthropy of making gifts to WashU Medicine to support research into Parkinson’s and Alzheimer’s diseases. After the sale of Scottrade, the couple established the Paula and Rodger Riney Foundation to support scientific research and general philanthropy, primarily in metropolitan St. Louis. Rodger Riney now serves on the WashU Medicine National Council.

Walensky, an infectious disease specialist and renowned authority on HIV/AIDS, served as director of the Centers for Disease Control and Prevention from 2021-23. During that time, she became a leader in the United States and around the world in the global response to the COVID-19 pandemic.
Prior to her tenure at the CDC, Walensky was a professor of medicine at Harvard Medical School and chief of the Division of Infectious Diseases at Massachusetts General Hospital, serving as a frontline clinician during the initial COVID-19 outbreak.
Walensky earned a bachelor’s degree in chemistry from WashU Arts & Sciences in 1991. She earned her medical degree in 1995 from the Johns Hopkins University School of Medicine and completed her residency in internal medicine in 1998 at Johns Hopkins Hospital.
Her medical training coincided with the peak years of deaths from AIDS in the United States, which provided the context for her fellowship in infectious diseases at Massachusetts General/Brigham and Women’s Hospital and for a master’s in public health at the Harvard School of Public Health, both completed in 2001. She joined the faculty of Harvard Medical School in 2001 and has published more than 350 articles on infectious diseases.
Walensky is a member of the American Academy of Physicians, the National Academy of Medicine and the Council on Foreign Relations. She serves on the boards of the Doris Duke Foundation and the Carter Center and is currently the Bayer Fellow in Health and Biotech at the American Academy in Berlin.

Yawitz, a three-time alumnus, is a former distinguished member of WashU’s faculty, an entrepreneur, business leader and philanthropist. The Yawitz family has invested deeply in St. Louis, with a special emphasis on economic development and education for children from underprivileged backgrounds.
Yawitz served on the faculty at Olin Business School for 14 years. During that time, he created and directed Olin’s Institute of Banking and Financial Markets and conducted pioneering research on fixed-income investing and interest-rate risk management that laid the foundation for his business career.
In 1985, Yawitz headed to Wall Street to serve as a vice president and director in the fixed income division at Goldman Sachs. In 1994, Yawitz and Bill Marshall, a fellow Olin faculty member and research collaborator, acquired National Investment Services of America (NISA) Inc. Over time, they transformed the firm into a powerhouse focused on the active management of fixed-income assets and derivative overlay strategies for institutional clients. Yawitz retired as chairman and CEO of NISA in 2021 after a multiyear transition of the firm’s management and ownership.
Yawitz has never wavered in his commitment to WashU. He and his family have provided generous support for endowed professorships and scholarships; WashU’s College Prep Program — which helps first-generation students from the St. Louis region prepare for college applications and college life; athletics; Olin Business School, the Department of Economics in Arts & Sciences; and WashU Medicine.
In 2006, Yawitz was inducted as the only wrestler in the WashU Athletics Hall of Fame. He has received a variety of notable WashU awards, including the Olin Distinguished Faculty Award, a Founders Day Distinguished Alumni Award and the Gephardt Institute’s Gerry & Bob Virgil Ethic of Service Award.
