Picture This...


Thousands of riders across the globe are doing Straightness Training (ST).

All they really want is a balanced horse and a harmonious relationship.

Sure, they can learn ST online, but a lot of them also need hands-on, in-person guidance.

That’s where you come in.

ST Instructors are in high demand.

We need certified ST Instructors who can handle this demand and provide the personal, live guidance STudents need to succeed.

I believe it's the greateST opportunity of our lifetime...

Meet Your New Career


There are literally tens of millions of horses in the world, and a lot of them are used for dressage, jumping, and ridden for recreational purposes.

All these horses all asymmetrical by nature, waiting for someone like you to STep up, and help them overcome the issues caused by natural asymmetry.

Fill a Gap in the Market


The most valuable skill that every single rider needs is Straightness Training, as only a balanced horse can carry a rider in a healthy and sustainable way.

But a lot of riders are struggling with stiffness and tension, because they don't recognize their horse's natural asymmetry:

❌ Unaddressed asymmetry can ruin not only their riding session but even their life.

❌ Riders are even losing their horses because of navicular disease and kissing spines.

✅ Imagine you coming in, helping them rebalance their horse—and all of a sudden, their unnecessary suffering comes to an end!

Be a Difference Maker


We call our ST Instructors game changers, rainmakers, and difference makers.

You’ll be like a magician— achieving real, visible and tangible results!

Imagine your students saying, "I can’t believe it—my horse feels so much more supple and responds so easily now!'”

Their lives will be better because of you and your skill set.

You, too, can STart the career
you've always dreamed off


You don’t need to be a professional, a veterinarian, or have years of experience. With the right education and certification (in the way I'll be showing you on this page),
you'll have everything you need to succeed!

From: Marijke de Jong

Location: Lisbon, Portugal

Dear instructor,

No matter your age, experience, or equestrian discipline... learning how to teach with my horse-friendly and proven "Straightness Training" formula can make a huge difference:

  • It can help you create your own teaching practice,
  • and give you the opportunity to turn your passion into a purposeful and profitable career.

 

Over the last 20+ years, I’ve helped thousands of equestrians go from feeling confused and stuck with their horse to feeling confident and moving forward by using Straightness Training (ST).

I’ve also had the privilege of guiding dozens of riders from knowing little about teaching ST to eventually becoming certified ST Instructors.

 

These certified ST Instructors now work in a wide range of unique niches, making a difference in various ways:

  • Teaching ST to kids and family horses,
  • Guiding STudents with gaited horses, OTTBs or a specific breed,
  • Integrating ST with jumping, vaulting, or natural horsemanship,
  • Specializing in horses with navicular disease or kissing spines,
  • Combining ST with careers as equine bodyworkers, therapeutic riding, veterinarians, or farriers.

 

If you want to make a difference and convert your calling into reality, then his certification program is for you!

Introducing

The ST Instructor Program

Introducing the

ST Instructor Program

The ST Instructor Program is the result of 20 years of experience with teaching thousands of STudents and certifying 125+ instructors.

It's the ULTIMATE, STep-by-STep training on how to become an ST Instructor!

However, I’m Keeping This Program Small


That way, I can maintain the integrity and quality of the training, and you’ll receive one-on-one coaching (
which we all know is the BEST way to grow quickly and effectively)!

That’s why I’m inviting only 8 people to join this month to become an ST Instructor— which includes classes, tools, live calls, and the knowledge to confidently help students train their horses. 

If you want to be one of those 8 people... and if you want the opportunity to create your own teaching practice...

❝Very happy to be on this next step to creating a better version of me in my lifelong journey of improvement. It's a wonderful group - I have always done things on my own and I feel this is a unique group of people to share my growth, my struggles and to be vulnerable and brave with. Thank you ST Community - let's go ST Instructor Program!❞

★★★★★

❝It is a very comprehensive and well thought through program. The right balance of involved guidance and independent study that ensures success. Loved the smaller class size. Really enjoyed the live calls and really enjoyed the lectures. Marijke is very enthusiastic. Her belief in our ability to become instructors was infectious. Her ability to put us at ease and help us find our confidence.❞

Michelle Masselink, Canada

★★★★★

❝I really liked Marijke’s personal approach and that we worked in our little group of peers. The course is very structured and provides all information, and during the calls, Marijke gave us, besides content, also time to ventilate, to speak about our concerns, and helped us through the obstacles we faced. In her approach, she embodies the ST coaching & teaching and exemplary shows up how to use self-mastery. With patience, understanding and compassion, she guided everyone of us on our personal journey. ❞

❝The content (classes, reading, worksheets) is excellent - exactly what I need - and is delivered in a perfect order. I felt prepared and confident when I was teaching real clients. For example, one of the clients was crying when we first met, but I could handle it perfectly. The content of the program is amazing, I am pretty sure it is the best program about teaching horse training. You don't have to have any prior teaching experience nor talent for teaching.❞

Polina Prikhodko, Netherlands

★★★★★

❝Comprehensive curriculum and the business side was a great addition. This was an area that I had little knowledge of and so am finding the material very helpful. Good range of assignments and assessment. It’s not as hard to do as you might think and you will learn lots of good stuff and also test yourself. You’ll meet some great people and when you pass you will have achieved a formalised pathway to help horses and riders.❞

❝The program covers everything! Marijke's coaching and teaching is excellent. The resources are all there. Structure and pacing are just right. You can do the program next to a busy life with work and kids. ❞

Anna van Rheeden, Indonesia

★★★★★

❝The program is well-thought out and very thorough. Quality is excellent. I enjoyed the mix of theory and practice. It gave me a chance to apply the theory I was learning to my work with my horse and my students. I loved meeting and working with so many awesome people from all over the world. Plus, it is so awesome to be able to work directly with Marijke. The opportunity to have lessons and feedback from Marijke was invaluable. I learned a lot.❞

Shelley, Canada

★★★★★

❝It is a great program, very clearly structured with all the needed tools (roadmap, calender, etc) and well organized. Everything is there. So many tools and concepts and well-thought-through materials. Great structure. I knew all the concepts and already had some experience in ST. For doing Grade 2, the 12 months were perfect for me. ❞

Simone Reindl, Germany

★★★★★

❝Very complete package with information and guidance that allows you to grow and practice with peers and new clients. In my experience the ST Instructor Program was not too heavy or too much to complete in one year. It is doable in one year, but I really like the 2 year concept, and it was very nice to know upfront that I have (at least :)) another year to deepen/broaden my ST experience. ❞

❝The body of knowledge and the never ending input of Marijke is in-cre-di-ble. This is next level Horsemanship. Especially the "observe first" (and know what to look for) and then progress in a structured way. It is a ground layer for every possible discipline. Other methods (I know of) focus on the rider and what to do to produce a desired outcome. ST focus is on the horse and what the horse needs to move forward.❞

Maarten Ducrot, Netherlands

★★★★★

❝It was excellent! Marijke’s incisive observation and keen listening supported by what seems to be never ending encouragement. Marijke's truthful and skillful reflection can be disarming in a way that my mind was then open to change. If you are looking for a real systemic way of understanding how to train for the horses optimal physical, emotional, mental and spiritual benefit and to understand the art of riding from the ground up this is the place for you!❞

Deborah Raoult, USA

★★★★★

❝I am extremely satisfied overall. Excellent material. The worksheets are one of my favorite parts, even if I just did one question it got me thinking and doing. Marijke has an excellent attitude, obvious skill, and I appreciate her mix of challenging and caring for each of us. If you’re considering the instructor program, Just Do it!
