A great way to catch your reader's attention is to tell a story.
Everything you consider writing can be told as a story.

Great stories have personality. Consider telling a great story that provides personality. Writing a story with personality for potential clients will assists with making a relationship connection. This shows up in small quirks like word choices or phrases. Write from your point of view, not from someone else's experience.

Great stories are for everyone even when only written for just one person. If you try to write with a wide general audience in mind, your story will ring false and be bland. No one will be interested. Write for one person. If it’s genuine for the one, it’s genuine for the rest.

Our office is located in the Wisseloord Area . The Wisseloord Area is located in the middle of the leafy residential area of Trompenberg in Hilversum. The office park merges with the wooded area. Hidden in green are five buildings, each with their own character. Parking spaces have been created between the trees.

The Wisseloord Area owes its name to the legendary Wisseloord Studios located on the site. The studios are world famous as many national and international artists such as The Rolling Stones, Elton John, Anouk and Marco Borsato have recorded their hits.

The atmosphere on the site is casual. Nature inspires. The area offers the opportunity to go outside, organize a brainstorming session under the trees or drink a cup of coffee in the sun
