Rachel Warners

Director of Organic Management

Rachel grew to love plants in the forests of West Michigan, tagging along on hikes and field trips with her botanist father. She followed her passion for restoration in college studying biology, environmental studies and Spanish. She spent her summers researching birds, working with a restoration nonprofit, teaching high schoolers about urban sustainability efforts, playing basketball with friends and enjoying the great outdoors. Coming from a long line of educators, Rachel’s passion for teaching translates into her work with clients—she wants everyone, of all ages, to learn to pay attention and interpret the world around them.

Rachel has been working as the Organic Management Director at Confidence Landscaping for two years after initially learning California ecology from teaching outdoor education in the mountains of Santa Cruz. She also works with California Native Garden Foundation as a volunteer leader and garden maintenance technician and returns to Michigan in the summer to lead a high school internship program in urban restoration. She is an avid hiker, camper, backpacker, beach volleyball and basketball player and lover of all things green.
