Jennifer Greene and Andrew Stellman have been building software and writing together since they first met in 1998. Their first book, Applied Software Project Management, was published by O’Reilly in 2005 and received widespread praise from both working project managers and academic researchers. Their second book, Head First PMP, was released in March 2007. It almost immediately became one of the top selling books from O’Reilly, and is still among the bestselling project management books today. Their books—a total of five books together so far, including two with second and third editions—have sold hundreds of thousands of copies, and have been translated into many languages and sold around the world.

Andrew and Jennifer founded Stellman & Greene Consulting in 2003, providing software development services and training to both companies and individuals. Andrew and Jenny continue to write books, presenting at conferences, and give back to the management community any time they have the opportunity to do so.

Jenny and Andrew want to help you build better software, whether that means helping you learn better ways to design and build code, adopt better practices, get a better handle on quality, or better understand your user. That’s why they love writing, and it’s what they love writing about.
