Grant S. Johnson is a filmmaker born, raised, and still living in Manhattan, NY. After graduating from Rye Country Day School in 2010, Grant attended Swarthmore College, where he pitched for the baseball team and majored in Art History. Shortly after graduating in 2014, Grant met Hunter Ryan and showed him his initial draft of Frat Star. Over the next six months, the two reworked the script, and entered preproduction in August 2015. The film was shot two months later and released by Gravitas Ventures and Netflix in early 2017.

The musical closed its Broadway run on August 5, 2018. Grant is also a producer with Hart and others on The Band's Visit (the Broadway musical), which won 10 Tony Awards including Best Musical. The musical closed on April 7, 2019. Both shows are touring nationally.
