    What I did? Managing education programs end-to-end. Mentoring instructors, planning events, and producing annual programs people actually remembered. Turning the agenda into experiences worth showing up for. And then making them bigger every year. What I didn't do? Sell Girl Scout cookies. Though the dedication level was pretty comparable.
