Pete became excited about treehouses at age 5 when his dad built him a treefort behind the garage of their Ridgewood, NJ home. The scope and size of Pete's treehouse fantasies expanded from there, but all of that appeared to run its course by the time he received his driver's license.Pete's 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", Pete embarked on a unique career path. The 1994 publication of Treehouses; The Art and Craft of Living Out on a Limb, the first book of its kind, has inspired him to write five more books on the subject. His latest book, titled Be in a Treehouse, details the technical aspects of building in the trees along with showcasing treehouses from all over the world.Pete runs Nelson Treehouse and Supply, a thriving treehouse building and supply company, and Treehouse Point, a treehouse Bed & Breakfast located outside of Seattle.His latest endeavor is hosting Animal Planet's hit television series, Treehouse Masters. He lives with his wife, Judy, in Fall City, Washington and has three adult children who he happily works with daily in the trees.
