After graduating from high school, Denise Tomrell trained as an event manager and then worked in event sales until she took over the management of the event office and thus the management of 6 conference rooms and the event location Kai 10 - The Floating Experience. Along the way, she obtained her trainer aptitude certificate and later her event management qualification. This was followed in 2020 by a move to the management of the Mercure Hotel Hamburg City.
