Drew Gramer Staff Scientist
Growing up I have always had a natural draw to the wild. Between gardening and landscaping in my childhood home’s backyard, frequenting the mountains on the weekend to climb a fourteener or go camping I have always been in awe of the natural world. I got my Business Administration, Management emphasis surrounded by mountains in Gunnison, CO at Western State Colorado University. I cannot imagine a world without “wild” places where everything has been developed and disturbed. I cannot speak for the great Aldo Leopold or John Muir, however their message of stewardship towards the Earth has always influenced my perspective on nature. Influence that I realized through working firsthand for an environmental company in nature we can start to unravel only the beginning of mysteries and questions that come with observing and preserving our wonderful diverse ecosystems available to us on Earth, so that others can share the same awe for generations to come. Based in Farmington, NM.
