Beach volleyball player Tom Sonneville (18) is a first-year student International Business Administration (IBA) at Rotterdam School of Management, Erasmus University Rotterdam (RSM). Like his sister, he plays beach volleyball for TeamNL: 'Sometimes there is competition, but we wish each other all the best.'
Volleyball family
Tom truly grew up with (beach) volleyball: 'My mum always coached the youngest kids. I went along, even before I was old enough to train. It was great fun. I was always in the hall and never without a ball.'
Tom now travels all over the world for tournaments. His sister, Noa, studies in America, but also plays for TeamNL. They see each other at the tournaments. And their parents? They faithfully travel everywhere to cheer them on. 'But it's not like they push us, not at all!'
It is very special that Tom can experience this with his sister: 'Sometimes there is competition, but we wish each other all the best! And because we're in the same situation, we understand each other. It's a completely different life, so it's nice to be able to share your story with someone who is experiencing the same thing.'
Indoor volleyball vs Beach volleyball
Tom has a sporting career in both "regular" volleyball and beach volleyball. How does that work? Tom: 'You start with indoor volleyball, which is also more popular. You can play volleyball anywhere in the hall. Beach volleyball is also big in the Randstad, which is close to the beach.' Volleyball players often start participating in beach volleyball competitions later on. Does Tom have a preference? 'I definitely prefer beach volleyball. That's why I quit playing indoor volleyball, so I could focus entirely on beach volleyball.'
In fact, as a beach volleyball player, you don't necessarily have to play on the beach. You can also play in a "sandpit". According to Tom, you see these more and more. Since 2024, there has also been a beach volleyball court at Campus Woudestein (read the news item on MyEUR).
Mindset determines performance
The mental aspect is very important, explains Tom: 'If you approach your training sessions and matches with enjoyment, you will always play your best and make the fastest progress.' Tom experienced a dip in his volleyball performance in the middle of the season, right after his final exams. But rediscovering the enjoyment in beach volleyball was the key to overcoming this.
At TeamNL, this is definitely something that is trained. Through conversations, for instance. Because the way you position yourself on the field – your attitude – is decisive for your performance. According to Tom, this is something that also comes in handy when studying: 'If you enjoy it, you learn more easily and absorb things better.'

'At high school, I was allowed to miss everything as long as I could maintain sufficient results. At university, there are more rules to take into account'

Guidance on studying and elite sport
Choosing the right study programme is already challenging enough, but as an elite athlete, you have to consider additional factors that can make this choice even more difficult. Fortunately, Tom received help from various sources during his study choice. An advisor from TeamNL has helped arrange meetings with Rebekka Kadijk, the elite sports coordinator at Erasmus Sport. In addition, he received support from study advisor Menno van der Hoorn at Rotterdam School of Management.
Notably, there is a difference between high school and university, says Tom: 'At high school, I was allowed to miss everything as long as I could maintain sufficient results. At university, there are more rules to take into account.'
Did Tom encounter any difficult situations during this first year of his studies? 'I missed one too many classes for one course and thought I wouldn't be able to complete it, but then Menno assisted me and everything turned out fine.'
Still, it's also a matter of trying out what works best for him: 'When I was in Mexico, I was allowed to take exams online. But in the end, it wasn't practical at all; I had to focus on the tournament, so taking exams in between is very difficult. However, it was nice that I was allowed to do it!'
During regular weeks, it’s actually great to have that variety between sports and studying. Tom elaborates: 'I am mostly occupied with my goals for beach volleyball. And I'm studying because I genuinely enjoy it, not because I have a specific goal for the future (yet). I imagine that it would be very difficult to map out two aspects of my life completely. At the moment, beach volleyball often comes first, but studying is also very important to me. When necessary, studying becomes temporarily my top priority.'
'Competing in two elite sports for several years is a remarkable accomplishment'
Menno van der Hoorn
Study advisor top-level athletes (RSM)
Double top-level sport
Menno van der Hoorn supports roughly 30 top-level athletes at RSM. As a study advisor for elite athletes, he is their permanent point of contact. He discusses the study planning in relation to their sporting activities. When bottlenecks arise concerning mandatory attendance, deadlines and examination, he tries to find a solution together with the student, in consultation with lecturers and the examination board.
Menno derives a great deal of satisfaction from his job: 'Sometimes it can be hard work because a lot has to be arranged at short notice, but on the other hand, most elite athletes are naturally disciplined, good at planning, and appreciate the guidance they receive. Obviously, it's also nice to hear their stories and follow their achievements in the media. In a way, it feels a bit like they are "my" students. I am always proud when a top athlete manages to get the most out of their sport while studying and simultaneously earns a degree. Primarily due to the achievement itself, because competing in two elite sports for several years is a remarkable accomplishment, but also because the objective of the elite sports policy has been achieved: to make the combination of top-level sport and study as feasible as possible.'
Moreover, not everything is possible, and there are conditions that top athletes must meet in order to be granted an exception. In addition, there are differences between faculties.
Travelling around the world
Meanwhile, Tom is also enjoying his IBA studies. His favourite course at the moment is Foundations of international marketing, and his favourite lecturer is dr. Alex Genevsky. And what does the future hold? This year he will be competing in the European Under-20 Championships and will need to collect points in the world tour in order to progress and develop: 'I am still a bit of a novice in the adult circuit.'
Tom truly enjoys travelling around the world through his sport: 'Last year we were in China, where they treat sport very differently. You're really seen as an idol there. It's very different from here and a special experience.'
