Hank Green

Hank Green started making YouTube videos 15 years ago with his brother, John. His love of the online community prompted Hank and John to co-found other endeavors, including VidCon, DFTBA.com, the Project for Awesome, and Complexly, which has produced nearly a dozen educational YouTube channels, including SciShow and Crash Course. Most recently, Hank and John are raising money to dramatically and systematically improve maternal health care in Sierra Leone. You can join them at PIH.org/hankandjohn.
