I love working at Mason because I love being able to support students at my alma mater as they build their student journey here especially as a marginalized identity

I joined the Staff Senate to help better support staff so they can better support their offices and audiences especially with topics not commonly discussed. I also wanted to learn more about the gaps we are seeing across the university and how we, as Staff Senate, can help mitigate them.
