Hi, I‘m Laura. I’ve been editing and writing for nearly twenty years, covering everything from developing a seismologist’s first book to telling the story of my first deer hunt. While the first half of my career was spent learning the ropes of publishing in New York City, for the second I’ve been in the wilds of the Pacific Northwest, working on projects for clients in the outdoor space. Most recently, I’ve been working as a senior staff writer at Outdoor Life. When I’m not at home with my husband and daughter, you can find me camping, backpacking, and running in the foothills of the Cascades.
