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 for Jill Tullman and Associates. Carson is teaching people how to use their assistive technology.
