FEI world number 1 and 2 time Golden medal winner European Championships 2025.
"The guidance of Sanne Beijerman and her encouragement have been invaluable in preparing me for my competitions with Zonik Plus this important year of our first European Championships. Her method and the work we’ve done together has been helpful to stay calm under pressure, to be 100% focussed on my horse despite a stressful environment and to boost my confidence significantly."
Olympic Rider
"Two years before the Olympic Games, I began working with sports psychologist Sanne Beijerman. Through this process, I got to know myself better as an athlete. Beyond learning techniques for focus and relaxation—such as breathing exercises— I discovered what kind of preparation works best, how to take control, ensuring that both you and your horse are in peak condition when it’s time to compete. For instance, I’ve learned that it’s crucial for me to be able to withdraw and have some time alone before I have to perform. Another significant aspect of this journey was that, at the time, making the Olympic team wasn’t one of my goals; I had simply taken the attitude of "we’ll see when the time comes." I learned to set those kinds of goals, which led me to train with much greater focus. As a result, I was indeed selected for the team and had the honor of representing the Netherlands in Tokyo."
Daphne van Peperstraten
European Junior Dressage Champion 2018
"Sanne's mental training has really helped me in my career to build self-confidence and set clear, bold goals without getting nervous about them. The training has greatly improved my mental fitness."
Esmee Donkers
European Champion Youngriders
"Together with Sanne, I always prepared carefully and mentally for the European Championships during my junior years. I learned to turn all the tension of major championships into something positive, learned how to focus 100% on what is within my control, and I truly know how to peak at the right moment. The medals I won at the Europeans, two golds, five silvers and one bronze, are proof of this. I still use the techniques today as a senior athlete, and I know I can always fall back on her guidance whenever needed."

"Sport psychologist Sanne Beijerman is a valuable member of my support team since the 2016 Olympics in Rio. I always prepare my big Championships with her and use her method and techniques to deal with the pressure, to set the right goals, to be in the optimal performance zone together and in harmony with my horses… This year despite the pressure this resulted in two amazing golden individual medals."
Pam Nieuwenhuis
Showjumper
“I’ve known Sanne since my pony years, when I first worked with her to improve my focus and sharpness. As a young-rider, when my best horse got injured and I had to compete with less experienced horses. I started doubting myself. This had a negative impact on my performance. It was a difficult time in my carreer. Sanne helped me once again by showing me how to turn my negative thoughts into a positive mindset, allowing me to enter the arena with confidence. Through my work with her I could clearly see my career goals again. Despite her busy schedule, she always takes the time for you and truly makes you feel supported.”
Nina Stegeman
Showjumper EK Childeren, silver team medal
"Where I stand today would never have happened without Sanne Beijerman's mental training.
I'm Nina Stegeman, and throughout the qualification process for the European Championship Children 2026, I received guidance from Sanne Beijerman. In the final qualifier, where all the training with Sanne had me fully focused, I managed to qualify for the European Championship."
Dominique van Dalsen
European Championships Junior Dressage 2025
"I worked with Sanne and her program in 2023 to prepare for the Europeans pony Dressage. I still use all of the mental skills, like my breathing technique to reduce stress and focus in an optimal way. Also for this Eurpoeans at Junior level I prepared with Sanne. I was focussed during the tests and really peak performed. I’m so proud of my indiviual silver medal, that really was beyond all expectations!"
Yessin Rahmouni
Three-time Olympian from Morocco.
“I am a very driven person and always give 100%. If a competition was important, I wanted to make it 200%. As a result, I became more impulsive in my riding and started reacting to my horse before anything had actually happened. This often led to miscommunication.
Before the Olympic Games in London, I started working with Sanne. I discovered that for optimal performance I actually needed to become calmer. I learned how to do that, and I learned to focus much more on positive thoughts and on the right interaction with my horse.
By now I have a highly structured preparation. I make extensive use of visualization, going through my test step by step. If I feel myself getting too tense during warm-up, I take a time-out and do my breathing exercises, which gives me more mental control.
The pressure was also very high at the Olympic Games in Tokyo. In moments like that, you automatically fall back into your old pitfalls. It helped enormously to be able to use the mental skills from Sanne’s method and to have short online sessions with her to polish the final details. That gave me the confidence to ride into the main arena.”
Danielle Heykoop
Team silver medal European Championship Senior Dressage
"When I moved up from U25 to the seniors, the process with Sanne Beijerman taught me to turn the negative thoughts that made me doubt myself into positive ones. This allowed me to build up my confidence. It also allowed me to make much clearer choices. That benefited my performance, including at the European Championship seniors, where I won team silver."
Diederik van Silfhout
Olympic rider
"As a junior, I experienced a lot of competition stress. Mental training helped me with that. The breathing techniques I learned, for example, were important in letting tension flow away. These techniques have now become unconscious, but I still use them.”
Mohammed El Serkal
UAE Champion 2025 and 2 time participant at the Asian Games
"Since 2023 I’v worked with Sanne, she plays an important role in my journey, helping me stay mentally strong but also transforming the way I see myself as a rider and in how I connect to my horses. She guided me through some of my hardest moments, helped me understand my emotions, and rebuild my self-confidence. Grateful for everything she helps me grow through towards the succesfull athlete but also the person I’m becomming."
