	Mackenzie Nelson Desert Institute Assistant Hello! My name is Mackenzie Nelson, or Kenzie for short. I am a recent graduate from the University of Redlands where I received a B.S. in Environmental Science and Spatial Studies (GIS). Our natural world inspires me everyday to continue to be a lifelong learner as well as help to engage others in the natural beauty and wonders that surround us. In my free time, I love hiking, biking, birding, kayaking, and reading. Southern California's deserts, including Joshua Tree National Park, have been places of refuge, relaxation, and reflection since I moved from Hawai'i to California a few years ago. I am very excited to work with the Desert Institute, its mission, staff, and all of you wonderful members and volunteers I have heard so many great things about! Pronouns: She, Her, Hers
