Peter N. Nelson became excited about treehouses at age five when his dad built him a tiny one behind the garage of their Ridgewood, New Jersey, home. The scope and size of Nelson’s treehouse fantasies expanded from there, but all of that appeared to run its course by the time he received his driver’s license. Unfashionably, his treehouse fantasies returned after graduating from college in Colorado with an economics degree. The carpenter and home builder within him could not be silenced, and with an eye to becoming "the treehouse guy," Nelson embarked on a career path unique in this age. The 1994 publication of Treehouses: The Art and Craft of Living Out on a Limb, the first book of its kind, has culminated in the publication of five more books on the subject, a thriving treehouse building and supply company, a treehouse hotel, and a hit television series on Animal Planet. He lives with his wife, Judy, in Fall City, Washington, and has three children.
