I guide horses & riders
Mireille Poeisz
My name is Mireille Poeisz and I've been working with horses for over 35 years. Over the years, I've gained experience as a rider, ORUN instructor, dressage trainer, and judge, both nationally and internationally. My approach is based on responsible training based on calm, balance, and harmony. I always guide horses with an eye for well-being, biomechanics, and sustainable development.

It turned out that my young Friesian horse, after being reared, needed to go to the equine clinic for surgery on its hind legs. A castration was also performed during that procedure. This had a significant impact on the subsequent period, and my initial plan had to be adjusted after the procedure. The clinic prescribed a strict three-month rehabilitation program, which I couldn't follow myself.
Through a mutual friend, I found Ocean Equine Wellness. I was nervous about entrusting my horse to someone else during that vulnerable time, but from the very first meeting, it felt right. And that feeling proved justified: my horse was cared for with so much love, peace, and care that I couldn't have wished for a better place for his recovery. And all of that in addition to the beautiful facilities and luxurious, spacious stables, which complement the high-quality care and the hospitality with which you are welcomed.
The rehabilitation plan was followed very precisely. What I particularly appreciated was that Mireille always considered any adjustments that were desirable or necessary. Her experience, knowledge, and expertise instilled great confidence. Options were carefully discussed, and choices were immediately implemented.
My horse came almost straight from the field and was therefore still very "green." Nevertheless, as soon as the schedule allowed, he was given daily exercise by hand. Thanks to Mireille's calm, respectful, and consistent approach, my young, untrained horse learned a lot during his rehabilitation and not only recovered well but also behaved well.
My horse has been through an intense process, both physically and mentally, since he left the rearing system, but thanks to Mireille's expert, careful, and loving approach, he's now a healthy, happy, and well-behaved horse in the pasture. I'm thrilled with him and can wholeheartedly recommend Ocean Equine Wellness.

Mireille is an exceptional dressage trainer. But even more importantly, she has genuine attention for both rider and horse. I felt incredibly fortunate to train with her. She possesses a very high level of knowledge and communicates it clearly and meaningfully, resulting in consistent and visible progress for both my horse and me.
Even outside of lessons, she always paid attention to my horse's well-being. From nutrition and effective training exercises between lessons to ensuring my horse always felt comfortable and happy—there's no one I would trust more with the care and training of my horse.

I'm very happy with Mireille's lessons! I received a lot of practical tips, both for training and competitions. It's great that she always works in an animal-friendly way and pays attention to the horse's well-being. Another advantage is that she also has experience as a judge; this allows her to really help with practicing tests, and I know exactly where to focus. Highly recommended!

Mireille is a fantastic dressage trainer, but above all, someone who genuinely cares about both rider and horse. I was incredibly fortunate to have her as a trainer. She possesses a very high level of knowledge and conveys it in an understandable way, allowing my horse and I to make constant progress together. Even outside of training sessions, she kept a close eye on my horse's well-being. From nutrition to effective training between lessons and ensuring comfort and well-being, there's no one I would trust more with the care and happiness of my horse. If you're looking for someone who truly cares for your horse and takes you to the next level together, you've found her.

Mireille is an exceptional dressage trainer who combines classical training principles with deep compassion for the horse and a clear, positive focus on the rider. She is genuinely committed to the well-being and development of each horse and offers well-thought-out exercises and training methods that encourage progress, while respecting both the horse's mental and physical health.
As a rider, working with Mireille is both instructive and inspiring. She is friendly, clear, and goal-oriented, always encouraging genuine collaboration between horse and rider. Thanks to her guidance, you grow as a team, with results stemming from balance and careful development, never from pressure or quick fixes.

I trained with Mireille for several years. She completely changed my perspective on dressage and patiently guided me through the transition to a new horse. Mireille has an infallible sense of what each individual horse needs and knows how to communicate this clearly to the rider. While I initially found dressage boring, Mireille made every lesson engaging with varied and interesting exercises. I looked forward to every session. She's a true professional with an enormous passion for helping both horse and rider reach their full potential.

The Netherlands can count itself lucky to have Mireille back. My daughter had weekly dressage lessons from Mireille for years, and the skills and knowledge she imparted at seventeen are invaluable. To this day, other trainers say she clearly had a very good dressage instructor. And I haven't even mentioned how Mireille works on self-carriage and correct biomechanics. Our horse's musculature, especially the topline, has improved enormously. We miss her terribly.

It was a privilege to have Mireille as my friend and instructor at my stable for five years while I trained my headstrong and temperamental mare. Our dressage scores clearly improved when we were able to train and prepare with her help. Her knowledge and communication skills make learning fun and understandable. I highly recommend Mireille if you want to improve your dressage skills and build a strong partnership with your horse.
