But, wait...

Q: Can’t I just learn what I need to on YouTube? you ask. What sets The Underswell method apart? Why pay for it? 

A: Sure, there are many, MANY, resources available on every media platform available. Some of it is good, some of it… not so much. Some of it is free, and some of it is very expensive. What it’s not? It’s not curated, organized, and systematically intended to get you efficiently and effectively from A-Z. From the core concepts to the latest state of the industry and everything in between. That’s where we come in.


The School of Understanding is based on the 3 different semesters that I created learning content for (and taught) while a college instructor. I started with an entry-level course that evolved to an intermediate-level course, which then ended with a more advanced concepts class.


And that is exactly what you get here. A progressive set of lessons that build upon one another based on my industry experience as a Merchandiser, Director of Corporate Responsibility, VP of Sustainability, and then sustainability consultant.

This is the course I wish I had while trying to figure it all out…

The School of Understanding is intended to sort through the chaos and noise and help you become confident and competent in the sustainability & climate change conversation as it relates to your work and your personal life.


Individually, each of our Lessons features:


✔️ 45-90 minutes of video lecture content (varies per lesson)

✔️ 10-question quiz to assess your knowledge

✔️ Links PDF - Get the links to topics/solutions mentioned in the lecture

✔️ Additional Resources - Where appropriate, we offer an accompanying page with other resources you might find useful to continue your learning journey.

✔️ 30-day access to your lesson*

✔️ 30-day access to our ever-evolving Member Resource Center and Community Support Space

*Course Packages feature longer access.

Going into the course I knew little about sustainability, and now I feel equipped to hold a job position in fashion sustainability. The course changed my life in how I see fashion, nature and the resources we use. I use the course principles every day of my life from the products I purchase to the food I eat.
