About Spark Plaza
Spark Plaza was started by husband and wife team, Jose and Shannon Castillo. Jose travels frequently and is forced to work in places never designed for work – airplanes, taxi cabs, coffee shops and hotel lobbies. After seeing several other co-working spaces in other cities, they decided that the Tri-Cities was ready for a better place for freelancers and entrepreneurs to work.
The Castillos were very intentional in the way Spark Plaza is designed – including the logo. The orange mark in the middle of the logo is a tribute to Jose’s grandparents, who met in an artist’s co-working space after World War II in Mexico City. The space was called “La Mancha”, which means the mark or the spot. The Castillos want Spark Plaza to be a place where others can leave their mark.
