The outcomes of the program really exceeded my expectations

After doing Katie's behavior design, I felt very powerful.  I can actually get people to do things, and I know it works because I tested it out. 


When I implemented my 7-day plant-based challenge, I had 30 people sign up and 15 people actually go through with the whole challenge, and people had a lot of fun. Especially the competition piece. I was amazed to see even the biggest meat-eaters so determined to get to the top of the leaderboard. I saw how powerful these simple tools are for behavior change.


That's when I realized – gamification works! Climate action can be fun, and that is exactly what we need to create change. With these new tools, I feel more hopeful about the future and feel like the world is my oyster. 😀

Fulfilling, inspiring and practical

For me, weaving and connecting different strategies into cohesive change frameworks was amazing. It removed a lot of the fear and gave me concrete steps for how to apply this work in the future.


Funnel design was completely new to me. Getting to explore things like landing pages and initial surveys was fascinating. We always expect people to “come to us” — but now I know how to be proactive!! I loved the experts you brought in. I can’t fit all of the ah-ha moments from those sessions into a sentence, but I’m pretty sure I had to turn my camera off a few times just to yell, “OH MY GOD. WOW.” at the ceiling.


Also, just personally, this has been such a fulfilling experience. I’ve been looking to learn about these topics for so much of my (short) career, and to find it all in one place has been incredible. Knowing that there are folks out there actually doing this work is also so meaningful — it gives me a path for the future.

Genuinely one of the best experiences I’ve had

This experience has stayed with me long after it ended. It’s been almost 6 months and I still find myself bringing it up in conversations about climate and behaviour change. The content was truly inspiring and insightful, sharing the most grounded, practical systems, frameworks and tips to move from climate awareness to climate action. Genuinely one of the best experiences I’ve had to learn how to drive climate ACTION!

The hard work is paying off!

Our journey with Katie was fantastic but, at the same time, daunting as she dissected what we'd developed from the ground up with a critical focus on improving long-term behaviour change. It required a healthy dose of humility as product designers to implement her recommendations, but the good news is the hard work is paying off. 


We're seeing users get through installation and setting up the App on their phones faster, with fewer support requests. More devices installed correctly, more data uploaded, more savings, and more delighted users. 


Katie is a world-class behavioural consultant. For anyone working in energy and water efficiency to drive behaviour change, Katie's Spotify podcast "How to save the world" is really worth a listen.

I absolutely loved it

The course was so interesting and so inspiring and so rich. We have these team check-ins every Monday, and every week I'd say, 'There's this thing I learned from Katie Patrick, this is what you need to know.' I have this tremendous desire to teach other people what I've learned, to help them have it in their own work.

Highly recommend Katie's Action School for anyone interested in sustainability change-making!

Katie Patrick is an expert on behavior change and breaks down complex topics in an easy (and fun!!) way. These workshops guide you through the steps to implement a program that actually gets people to change their behavior so that we can make climate action real.


It helped me see how behavior-change tools are like "ingredients in a recipe" we need to design, rather than hunting for the one silver bullet. 


I particularly love Katie's recent newsletter exploring the intersection of systems change and individual action. This is key for our students to understand.

I just did a pitch using your hero's journey for a funder. And it went so well. We got through to the next stage and now have 7 sites now composting on our programme :) 

I feel extremely confident now. I can't even remember how I felt before the Action Design School. I feel like we are in the bud stage and nothing can stop the serious flowering that will be happening soon. 


I so appreciate the Hello World site, and I can't wait to spend more time in there and keep learning.

Strongly Recommend, Very Challenging!

The course was very challenging, and it took me a lot longer to uncover what specifically I could do on Renourish Studio to shift designers to use circular design in their studios. However, Katie Patrick was amazing and spent so much time with all of us, guiding, inspiring, leading, and challenging. She provided great feedback on our initial ideas, pushing us toward one that would help create more effective behavior change. I highly recommend it and encourage you to apply to help promote more impactful climate action.

I learned so much

Katie brings behavioral psychology, marketing, and funnels together into a practical system. Even mentoring a youth 'no-buy' campaign with a limited budget, I could apply the steps and see how they move people from knowing to doing. Compared to other courses I've taken, this kept me on track. There was real homework, the expert talks and recordings were invaluable, and the community was supportive.

Her innovative approach and extensive knowledge of science-backed behavior change methods energized the design process and ultimately contributed to the development of a powerful tool that is now empowering users across the country.

For a company specialized in virtual universes, the message was spot on and landed very well! Thanks again.
