Hi, I'm Dr. Jillian (Goetz) Wong. I earned my PhD in Neuroscience in 2015 and performed postdoctoral research at Northwestern University until 2020. When I realized that I wouldn't be able to teach as much as I'd like if I continued as a professor, I decided that I needed to find a better outlet for educating students. Mathnasium was my key!
