Kate’s love for nature started when she was a kid, spending hours outside imagining, exploring, and sometimes hiding in her secret fort of azalea bushes in her backyard.

Kate believes that spending time in nature is essential for children's physical, emotional, and social development. She is passionate about connecting kids and their families to nature and one another through playful outdoor learning experiences.
