The secret behind our success - and yours

The six keys of Straightness Training

  • The foundation of the ST Academy is causal coaching. We don't fight the symptoms. We focus on finding the root of the problem.
  • Our logical system of progressive exercises can solve any problem that is caused by natural asymmetry. Learn and apply these exercises and then pass them on to your students.

What Sets You Apart As Instructor

The unmounted training pillars of ST set you and your students up for success


Groundwork is were we start to counteract the eight dimensions of natural asymmetry.


With longeing, each horse can learn to how to 'turn' instead of falling on the inside or outside shoulder.

Work in hand

Many riding problems can be solved in work in hand, and it helps us prepare our horse for ridden work.

Why Make Big Decisions Alone?

Schedule your 20-minute call, and discover if becoming an ST Instructor is right for you.

  • If you take this decision seriously, then you can book a 20-minute STrategy Call on Zoom with me. 
  • I want you to know I respect your final decision, so when you hop on this call, all the pressure is off. 
  • I know that sometimes it's genuinely not the right time to jump into a program like the Basic ST Instructor Certification Program (BCP). And, hey, telling you to jump in when you're not ready creates 10x more work on me, so I won't tell you BCP is a fit if it isn't. 
  • But I also know that sometimes one piece of information is all you need to have the confidence to jump in, and I genuinely care about you and those big, beautiful dreams of yours, so I just want you to know that I'm the person with the details :-)
