Sponsored by Iwan Simonis since 2019, the Dutch 3-cushion Champion who is considered as a Legend in her sport will now be sponsored by both the world’s leading billiard cloth and ball manufacturers.



Born in Nijkerk in 1983, Therèse Klompenhouwer discovered billiard in the café her father owned. She started really getting into it at the age of 8, using a stool to climb and hit balls. She first played Libre and at the age of 19, she switched to 3-cushion. She was quickly selected in the National Dutch team by the KNBB, the Dutch Billiards Federation. In 2004, she won the Dutch championship, her first main title.

From there, Therèse Klompenhouwer started piling up titles and the Legend was born. The one called “The Queen” by the public and opponents has won 4 Grand Prix titles,16 National and 11 European championships, and has been 5 times World Champion in 2014, 2016, 2018, 2019 and 2022.

In 2016, Therèse Klompenhouwer became Honorary member of the KNBB and in 2019, she received the Royal award knighted “Ridder in de Orde van Oranje Nassau” from the Dutch government.

Therèse Klompenhouwer: “I have a partnership with Simonis for several years now. Simonis has been manufacturing high-quality cloths for decades. It is the best and most consistent cloth for me. Now with Aramith also as a partner, I am sure that I can always train with the best equipment. The Pro-Cup Prestige balls always give me the right control over my shot. They always roll perfectly and correctly, and they last longer than any other balls… THE perfect combination! I look forward to my collaboration with both Simonis and Aramith! I am grateful for their belief in me and for their support. Let’s claim many more titles together!”

Jérôme Poncelet (Group Commercial Director): “It has been a honour to have Therèse as one of Simonis ambassadors these last 4 years and we are glad to renew this partnership for the coming years. As Simonis 300 is the main Carom cloth used worldwide in tournaments, it is important for us to have this kind of collaborations with very talented players who make the History of their sport. Regarding Aramith, It is a privilege for us to start this partnership with Therèse. Super Aramith Pro-Cup balls are used in most amateur and professional Carom events worldwide. We will follow closely her future achievements and she can be assured to have the support of both our brands to win many more titles.”
