After graduation, she worked for Cincinnati Gas & Electric Co., which later became Duke Energy. She helped break barriers as a new business development officer in the trust department at Fifth Third Bank. She continued her career in commercial and residential real estate.
Along the way, Rieveschl volunteered her time to support many important civic causes and charitable endeavors. She was the first woman president of the Mount Adams Civic Association and served on the board of the Covington Rotary Club, the Carnegie Arts Center and the Cincinnati May Festival.
Rieveschl has been a passionate supporter of higher education. She was appointed to the UC Foundation’s Board of Trustees in 2010 and serves on its Committee on Trustees and Governance and its Executive Committee. She also serves on the Northern Kentucky University Informatics Council.
She served as an honorary co-chair of UC’s 2008 “Proudly Cincinnati” campaign, which raised more than $1 billion from nearly 92,000 donors. The campaign helped support UC’s Goering Center and Sheakley Athletics Center, among other campus projects. The campaign provided more than $100 million for financial aid and scholarships, and funded $171 million in UC research.
She also devotes her time to the arts, supporting the Taft Museum of Art, Cincinnati Symphony Orchestra, the Cincinnati Museum Center, the Lloyd Library and Museum, among other organizations.
Taft Museum President Debora Emont Scott said Rieveschl has been a valuable board member, particularly in her leadership position as chairwoman of the Governance Committee.
"Most recently Ellen has taken on a leadership role as chair of our Governance Committee. In that role she has been instrumental as we renew and improve our policies and operations," Scott said. "She is respectful, inquisitive and extremely dedicated to the numerous organizations she supports philanthropically. I am grateful to count her as a trusted advisor and loyal supporter."
Rieveschl’s late husband, Benadryl inventor George Rieveschl, was a UC graduate of the College of Arts and Sciences. After a long career in the pharmaceutical industry, Rieveschl returned to UC to serve as vice president of research. He founded the UC Foundation and McMicken Society. Rieveschl Hall on UC’s Uptown campus is named for him.
