Optimize your knowledge and skills, so you can actualize your horse's potential


What we do

The ST Academy helps you to achieve mastery in three areas. 

Mastery of Oneself

We help you shift boundaries within yourself, so you can achieve harmony in your own body, mind, heart, and soul. 

Mastery of ST

Learn how to rebalance your horse physically, mentally, emotionally and spiritually by using Straightness Training.  

Mastery of The Horse

Through mastery of oneself and ST, you can create real beauty and bring out the magnificent giant your horse can be.

How it works...

Two opportunities to get the most out of yourself.


Marijke de Jong founded the international Straightness Training Academy in 2013 with the goal of helping riders create an amazing relationship and magnificent life with their horses - wherever they are in the world.

Marijke has coached thousands of riders individually and in groups to improve their horsemanship, their training skills, their horse's well-being, and their own lives.

Through the ST Academy, Marijke has created the online group coaching program, called Scholars, as well as the Certification Path:

Your transformation is our success


It's our mission, to help you transform into the effective Straightness Trainer you're meant to be.  

In the Straightness Training Academy, we already helped thousands of people all over the world.

And we'd be honored to work with you too!

Nice To Meet You!

"Hi, I'm Marijke.


I help equestrians go from feeling confused and stuck with their horse to feeling confident and moving forward. 

I believe no one should have to face with unnecessary suffering because of unaddressed natural asymmetry.

Every rider and horse deserves balance in body, mind, heart and soul, and a great working partnership together.

I also believe you and your horse are designed for more.

When you are the next-level version of yourself, when you’re showing up as the best horse trainer you can be, you cannot help but make a positive difference for your horse.

You can even be the change you want to see and have a positive impact on the people around you.
