2024 NCOSE staff page does not list Stefanski, nor does the 2022 staff page, but she is listed on the 2021 staff page. But she has a small picture, while there are 12 people with big pictures. The NCOSE's 990s only list 10 or 12 people, so I suspect the reason Stefanski doesn't show up on the 990s is just that she wasn't senior enough. So on this count, I'd say the reddit post is wrong.
