Carson Covey

Carson graduated from Chatfield High school in Jefferson County in May, 2018.  He previously worked at Jill Tullman and Associates during summers, and he now works at Jill Tullman and Associates.  Carson has cerebral palsy.  His first experience using assistive technology was in 2004 when he got the Pathfinder, a communication device from Prentke Romich Company (PRC).  He picked up on using this device very quickly and used it for many years.  His next talker was the ECO, also from PRC.  Carson had all of his school apps on an iPad.  Once Carson’s ECO died, his family called Jill Tullman and Associates. Carson’s mother wanted to know what talker apps were available for the iPad because at one point Carson was using his communication device to talk and his iPad for all school work.  Jill Tullman got him set up with a new iPad with communication apps. Two years later, Carson was working at Jill Tullman and Associates. Carson manages our social media, serves as a mentor, and is teaching people how to use their assistive technology.
