Aaron Hillegass worked at NeXT and then Apple before creating Big Nerd Ranch, a training and consulting company that specializes in Mac, iPhone, and Open Source technologies.
He lives in Atlanta, where Big Nerd Ranch teaches most of its classes. These classes have led to the creation of a series of books: The Big Nerd Ranch Guides. These books follow a consistent style that features a hands-on approach and a clear and conversational tone.
