At Treehaus Studio, we emphasize collaborative teaching, where artists, scientists, naturalists, adventure guides, wellness practitioners, and thought leaders unite to create transformative experiences for you

methodology
Transdisciplinary collaboration happens when individuals from different fields, such as the arts and sciences, work together to create an experience. This approach encourages participants to interact across disciplines throughout the entire process rather than working in isolation. Each person contributes their unique perspectives, skills, methods, and ideas, which enhances the overall result.
