This year we also took the immediate past president to dinner because last year’s dinner was cancelled as a consequence of Covid-19. The number in parenthesis is the year they served GSW as president. L. to R. on the front row we have Linda Rowan (2011), Rosalind Helz (1994), Ester Sztein (2020), Liz Cottrell (2021), Karen Prestegaard (2018), Mary Horan (spouse), Jane Hammarstrom (2000), and Lynn Shirey (spouse).
