Rosemarie was such a supportive and helpful colleague at the Tepper School - she was so willing to help navigate complex and challenging projects with incredible patience and kindness; she always seemed to know just what to do. It truly was a pleasure to get to work with her. She was always a supporter of the Tepper Staff events, and it made my heart smile knowing that she and the TAS team would be there - she was always a contributor to the collective good. My condolences and sympathy to her friends, family, and loved ones.
