Confidential contact person

The ACLO wants to offer a safe sports environment in which everyone feels at home. Together we do everything we can to prevent transgressive behavior such as bullying, conflicts and arguments, discrimination and sexual intimidation within our foundation in order to ensure a safe sports climate. That is why the ACLO has appointed two confidential contact persons. They act as a central point of contact to ensure that the way in which we interact with each other is respectful and safe.

You can go to the confidential contact persons with questions that you do not easily ask or that you are afraid that will not be answered seriously. This applies to all ACLO athletes. In addition: reporting quickly, talking about it and ensuring that an undesired situation is (early) put an end to, ensures that it does not worsen and that recurrence is thus prevented.

Leon Hovenkamp

My name is Leon Hovenkamp and together with Velda I am the confidential contact person at the ACLO. I have been studying in Groningen and am currently completing my master’s degree. Besides that I am also a big sports fan. Soccer, volleyball and road cycling make me the most happy. I got to know student sports well during the 2020-2021 year when I was allowed to hold the position of president on the ACLO Executive Board. In the years following my board year, I joined several student sports associations to contribute to student sports in Groningen. The student sports in Groningen is a place where there is no room for undesirable behavior and where everyone should feel safe. Therefore, please be sure to contact us if you experience inappropriate behavior or have the feel that inappropriate behavior is taking place. I will offer you a listening ear, advise you and handle the situation with discretion. Should something come up, do you have questions, or would like to talk about a situation, you can make an appointment at
