Are you stuck at trying to layer with gouache?
How about controlling the consistency of gouache?
  • Looking for a way to be able to control gouache better?
  • Want to use gouache to depict light and shadow?
  • Ready to build your confidence in a medium that is growing in popularity?

If you've tried to DIY it before, you know how difficult it can be to layer with gouache. I'll show you everything you need to know in order to handle the medium of gouache in  all  situations, and a step-by-step method  for  painting that can carry into any opaque medium!

Gouache Made Simple
  • 4 hours of instruction a week, 2 classes a week, for six weeks. (24+ hours of instruction)
  • Classes delivered live via Zoom, 5-7pm Pacific time

If you’re tired of your gouache practice being a mess, and not having a direction...

My ECR Method of Establish-Compare-Refine walks you through the exact steps you need to follow in order to create a great painting. It’s so logical and straightforward, yet leaves so much room to express yourself!

Do you love painting in oils but are getting tired of the set-up or cleanup?

Interested in the ease of set-up, as well as the portability?

  • Feeling in a rut?

  • Feeling like you're taking one step forward, two steps back in your painting process?

  • Need an expert eye to steer you away from bad habits and help fix your mistakes?

I'm here to help.

When I first learned to use gouache, it was done in a way that was very rigid and not very fun...

It wasn’t until I saw artists treating it as a true painting medium and not just for design that I was opened up to the world of gouache as a legitimate fine art medium.




Even so, it took me years of learning, trial and error, and experimentation to get to where I am today.

That's why, in just 6 weeks, you will see a transformation not only in your understanding of gouache, but in your understanding of painting at large! These are lessons that you will be able to take into other media beyond gouache!

You've got a master of gouache living inside of you.

Don’t hesitate to bring that master out of you!

Professional Fine Artist, San Francisco Bay Area

Humble beginnings as a creative person can lead you down a path to make your dreams realized in the future with enough hard work. 


What I hope to bring to the world is an understanding of the importance of beauty for the human soul by creating the most beautiful awe-inspiring works I’m capable of, and helping others create their art at the greatest capacity, then communicating why these works matter. 


My paintings are the truest representation of what I want to express and what I believe to be the best representation of what I consider beautiful. They present my skillsets in all facets to the highest degree and what I want you to have the ability to access.


Since beginning participation in events in 2010, I have won the Carmel Art Festival in 2017,  Sonoma Plein Air’s grand prize award in 2013, the Valona Paint Out best of show award twice, 3 awards in the San Clemente Festival, and many more.

This course shows you everything you need to learn about gouache in detail from wherever in the world you are!

You don’t need another free Youtube video or Instagram Live to try and piece together your gouache education. You need a teacher to guide you through the process and showing you actionable steps toward mastery!
