Prior to the Million Person Project Julian was a founding team member of Green For All. His career is fueled by a strong belief in authentic movements that are powered by people. To this end, he’s engaged thousands of young people in the climate movement, by organizing educational engagements on tour with Drake and Wiz Khalifa, and by organizing Green For All’s College Ambassador program, which cultivates environmental leaders at Historically Black Colleges and Universities.
In 2015, Julian was recognized by Huffington Post as one of "10 Leaders reshaping the Environmental Movement.” Julian and his Partner Heather Box were recognized as one of 16 projects to watch in 2016 by Grist, and Julian was a member of the inaugural "Grist 50" environmental change makers list. In 2019, Julian published his first book with Chronicle Books (co-authored by Heather) How Your Story Sets you Free.
