Use The Power Of Self-Mastery

After 7 years of experience with the Straightness Training Academy, with thousands of enthusiastic Mastery students, we'd like to take it a step further!

We're very proud of our Straightness Training students and their results with their horses, and it's our ambition to increase our impact even more! To be even more life-changing! No matter the level of skill or the age of our students!

We'd like to take the fundamental work with horses to a higher level by not only focusing on mastery of Straightness Training but also on mastery of oneself.

In the words of Leonardo da Vinci (1452-1519):

❝ One can have no smaller or greater mastery than mastery of oneself ❞

Leonardi da Vinci was a so-called "Renaissance Man", which is a person who is an expert in a wide range of different subjects and areas of wisdom. The reason why he mastered many crafts was that he used his full potential.

He used the power of self-mastery.

Make The Most Of What You've Got

Leonardo da Vinci and other Renaissance Scholars had a growth mindset and focused on developing their capacities in body, mind, heart, and soul as fully as possible at any age. Thanks to a balanced body, a curious mind, an open heart, and a peaceful soul, mastery in any other aspect of life was much easier.

In the ST Academy, we apply this wisdom to help you become the good horse trainer that you're meant to be. 

We use the power of self-mastery to grow your ability to make the most out of your physical, mental, emotional, and spiritual health so you can actualize your potential. 

Unlock Your True Potential

Self-mastery not only develops you as a human but also gives you the ability to be successful in Straightness Training. 

Self-mastery helps to create a vision for your future self and to find meaning in challenging times. 

Through self-mastery, you can break through resistance.

You learn to master yourself by getting out of your own way.

Through self-mastery, nothing is holding you back!

Go Out Of Your Own Way

The ST Academy is designed to assist you on your personal path to mastery.

You've barely scratched the surface of what you can achieve, and you know it!

But my guess is, since you're reading this, you're ready to change all that.

Whether you're a total beginner, an ambitious leisure rider, a professional horse trainer, an equine therapist, an instructor - whoever you are, and whatever you do, there's one thing that's certain:

You are ready to become a next-level horse trainer.

Like a true Renaissance rider who is clever at many things, who keeps learning and growing to become the best version of oneself. 

Ready To Change Your Life? Let's Go...

In the Scholar Programs of the ST Academy, you can find your own personal freedom, and become this next-level horse trainer by 'training' oneself in the spirit of the Renaissance men and woman.

These Renaissance Scholars strived for constant and never-ending improvement in their body, mindset, emotions, spirit, crafts, skills, and many other areas of their life to be able to create things of beauty and worth.

No matter how much doubt you currently have, you can truly change and create lasting change.

You just need a different approach.

Therefore, every month, you'll get new insights and resources on topics like:

  • Overcoming Obstacles
  • Feeling better
  • Getting More Done
  • Creating good habits
  • Developing Confidence
  • Getting Your Mojo Back
  • Starting Over
  • Keeping Momentum
  • Staying Focused
  • Getting Results
  • Finding Meaning
  • Making Impact

Start your transformation now to living a better quality of life, and reach long-term success. 

The ST Academy Scholar Programs are designed to help you transform into the good horse trainer you're meant to be so you can turn your (difficult) horse into a dream horse!  

The PRIMARY Scholar Program

This is a great program if you're completely new to Straightness Training. As a Primary Scholar, you'll EXPLORE the world of self-mastery and Straightness Training. You'll get lessons on life-changing topics that help you achieve more and live a happier, healthy, more balanced life. Each month, you'll get access to the following resources:

The PREMIUM Scholar Program

This is a great program for riders who have a bit experience with Straightness Training. As a Premium Scholar, you'll EXPERIENCE self-mastery and Straightness Training on a deeper level. You'll receive all the monthly resources of the Primary Scholar Program, PLUS, you'll get access to:

Premium Scholars Also Get Access To The ST Evaluation Program

This program contains an exclusive collection of hundreds of lessons. You can watch groundwork, work in hand, longeing, riding, and liberty lessons. Lessons with novice and more advanced riders. With young horses, senior horses, and all ages in between. With mares, geldings, and stallions. Warmbloods, thoroughbreds, gaited horses, and many other breeds.

Access to this library is of great importance to fast track your growth, and it's an invaluable support on your ST journey! And when joining the ST Academy as a Premium Scholar, you get instant access to this library of lessons!


The PRIVATE Scholar Program

This is a great program for riders who are no longer a beginner in Straightness Training. They have been a Premium Scholar for at least 6 months, and have achieved at least Grade 1 in the ST Evaluation Program. As a Private Scholar you'll be able to EXCELL in self-mastery and Straightness Training.

HOWEVER, this membership will most certainly not be for everyone... only if you are at the point where you want to get the next level and accelerate, and are ready to empty your cup, treasure your beginner's mind, and are willing to use the two magic powers that fuel success, than this might be the Scholar Program for you.

As a Private Scholar, you'll get access to the resources of the Primary AND Premium Scholar Programs, PLUS, Marijke will coach you personally with:

All Scholar Programs Include Access To the STclopedia

The encyclopedia of Straightness Training helps you learn the skills, strategies & tools you need to actualize your horse's full potential in body, mind, heart, and soul. 

As a Primary, Premium, or Private Scholar you get access to this STclopedia, and to avoid overwhelm, we will serve it into bit-sized chunks in the form of monthly Mastery Lectures so you know exactly where to start and what to do next.

The STclopedia is broken down into 12 Mastery Modules with Lessons with supporting video content and complementary manuals on how to do groundwork, longeing, work in hand, riding, and Straightness training at Liberty.

Every month you get access to another set of Mastery Lessons that will help you fast-track your growth, achieve extraordinary results, and save you years of time-consuming trial and error.

Join the ST Academy To Help Your Horse - And Make A Measurable Difference To Other Horses Too!

When you invest in your success through the ST Academy, you're not only helping your own horse, but you're also helping other horses in need. 

We believe that animals need to be treated with respect, love, and care. Especially the over 100 million working horses, donkeys, and mules who provide invaluable support to the daily life of an estimated 600 million people in some of the poorest places in the world through transportation and production. Healthy working horses, donkeys and mules help to put food on their owner's tables, send their children to school, and build better futures for themselves and their families. 

Our goal is not only to help you make a positive change for your horse but also to make a positive difference for horses, donkeys, and mules in need. That's why a portion of profits from our company go directly to non-profit organizations that support horses, donkeys, and mules in need.

Here's What You'll Get When Joining The ST Academy

Whether you are just starting out, or want to take your advanced skills to new heights, the ST Academy can help by providing crucial elements vital to your success!

When you cancel your membership, you have to wait one full year before you can return to one of the Scholar Programs.


No, it’s not possible to purchase isolated coaching elements of the Premium Membership.


 It has been a deliberate choice of us to start the ST Academy in the new format to really help riders to transform their lives and that of their horses.


Based on the experience of the past, using individual coaching components of the ST Academy in an isolated way won’t create long-lasting change.


We really believe in the compound effect of all the individual coaching parts – the workbooks, the assignments, the group classes, the Hot Seats, the Breakthroughs, the Touchstones.


We really want to focus on helping Scholars transform and create long-lasting change through an integrated approach and a compound way of coaching in the Scholar Programs.
