Oliver Dippold

Ever since I was a child, I have been fascinated by scientific and technical progress. I see it as a privilege to be able to experience this to a great extent. I see it as my duty to apply this knowledge to optimize processes in our own company and at our customers. The urge to constantly acquire new knowledge is accompanied by a quote from Philip Rosenthal: “Those who stop getting better have stopped being good.”

Eugenia Stotz
Marketing & Communication
Not only do I love being able to support people in the creative field,
but also to enthusiastically build, maintain and develop communications and customer relationships.
My motto in life, which has been with me for a very long time, is:
“Everything happens for a reason.”

Sabine Rothemel
Management assistance
As the youngest pioneer, I am actually not the youngest. However, I and thus also the team can build on and benefit from my many years of experience in the service and training sector.
This allows me to be open to new ideas, to try things out and to allow creativity.
This offers me a broader perspective. It is particularly important to me to change perspectives – my own and that of our customers.

Willi Scherer

Originally, I had planned to work with computers, but now I’m a pastor. I get my motivation from deadlines, my drive from carbohydrates, and the only thing I enjoy is serotonin and dopamine.
