Growing up, we're often told to follow our passions. Some of us do, some of us don't. What General Assembly (GA) is trying to do is give people the option, even if you think that ship has sailed. The New York-based company started out in 2010 providing part- and full-time courses for anyone to change careers or add new skills. Today, it's expanded that mission by partnering with companies to introduce new talent and train existing employees. So whether you're a marketer who wants to learn front-end development, or someone with technical chops with interest in graphic design, GA is here to help.
