Keylie Knegt

Chair

Meet Keylie, ready to take on the role of chair for the second time! She’s been a part of Deltaserat for 5 years now, and it’s safe to say that the club has become a big part of her life. The friendly atmosphere, the sense of community, and of course, the people are what made her fall in love with Deltaserat. Keylie started out with kickboxing and has recently added MMA to the mix. But there’s more to her than martial arts! In her free time, she loves travelling, drawing and painting, going to concerts and the cinema, hanging out with friends, and cooking up delicious food. As chair, Keylie helps organise everything that goes on in the club. So, if you have any questions, ideas, or want to get involved and help out, don’t hesitate to reach out to her!

What you need to know about our chair:

- She manages the structure of the association and checks our overall progress throughout the year.

- She is the first point of contact between ACLO and our association and you can go to her with any concerns relating to this communication.

- She keeps track of trainings to make sure that they are all running smoothly and according to the wishes of our members.

- You can always come up to her if you have any questions, to share your concerns or just to have a chat!

Cosmin CÎrlan

Secretary

 

Meet Cosmin! After 8 years with the club, he’s now stepping up as the new secretary of Deltaserat. What kept him coming back? The intensity of the training, the skills of the coaches, and, most importantly, the community that makes this club feel like home. Starting out as a grappler, he went on to try pretty much every martial art Deltaserat has to offer (and then some!). These days, you’ll mostly find him at Kickboxing and MMA training. As secretary, Cosmin will be the link between the members and the board, helping everyone stay connected and informed. So, if you have any questions or need something clarified, don’t hesitate to reach out!

These are the tasks of our secretary:

- Covering communication between the board and the members of our association.

- Making announcements for upcoming events and socials.

Joining initially to learn martial arts and get more fit in the process, Dennis has stuck around for the warm atmosphere and the community around the club. On the mats, Dennis is a tenacious and technical fighter, able to close in on and then pick apart his opponent. Apart from his studies and training kickboxing, he likes to play the piano and pool in his free time. As treasurer, Dennis manages the clubs finances and memberships. If you have any questions about memberships, payment options or anything else related, feel free to contact him!

Meet Kasper, our new external affairs manager! Hailing from Leiden, Kasper has been practising martial arts since his youth, joining Deltaserat 2 years ago to practice Kickboxing. With his intense stature and confidence, Kasper is a formidable foe on the mats who never backs down from a fight.

In managing these events, he effortlessly rallies together our members to strengthen our community.
