Marshall “Gripp” Gillson is a nerd by day and an artist by day also. He has been an active slam poet since 2008, representing six different venues in four different states in national competition. He appeared on back-to-back National Poetry Slam final stages in 2016 and 2017 as a member of the House Slam team and placed 15th in the 2014 Individual World Poetry Slam. He was also a member of the winning team at the 2016 Vox Pop slam tournament. His work has appeared in several self-published chapbooks and electronic art installations as well as being featured by Button Poetry, SlamFind, Everyday Feminism, and SlamChop.

In 2011, Marshall officially founded glassEyeballs, an artist services company. Under the brand, he provides workshops, poetry shows, and technical artist services, including overseeing the web-based scoring systems for six national poetry tournaments. In his spare time, he enjoys shuffling awkwardly, hiding from his problems, and writing biographies in the third person.
