Steven Koszis

Co-Founder of DoorJamm

Steve Koszis has been a police officer in Glendale for the last 7 years and co-founder of DoorJamm. He developed a reliable and reusable tool to prevent doors from locking behind police officers and firefighters. He was frustrated by constantly having to improvise in some way to block open security doors and gates he encountered on patrol. DoorJamm improves the safety of all first responders. 

Steve earned an MBA from Cal State Los Angeles in 2008. While studying business, he successfully developed and sold another product business.
