As Crescendo, we are sponsors of football club Hollandia which is well known in Hoorn and the surrounding area. For us, not only the selection is important, but the entire club with all teams playing sports in the Hollandia shirt on a weekly basis. In the national football league, we sponsor football clubs AZ and Ajax in various expressions.

We also attend the annual Iron Man which takes place in the West Frisian countryside. This triathlon is swum, cycled and run in and around Hoorn. We accommodate the construction and logistics team, which each time performs a great feat by taking care of facilities such as supplies for posts along the course, road closures for runners and cyclists, setting out a swimming course and building the finish location. Of course, with a lot of help from a large group of volunteers from the various regional (sports) associations.
