Dear visitors,

welcome to my private page.

Again and again the question arises in one or the other conversation, who is Ralf Semmler actually and what is he doing? Therefore, I hereby give you an insight into my person and my activities.
Through my countless travels in recent decades, whether privately or on business, I have had to get a very good view of the world.

You can not buy this experience, you have to experience it. Our children can share this experience with their life journey and hope that in the future they can be happy and happy.

It is an exciting time at the moment and will remain for the next few years. It will be a great challenge for all to survive the trade-off between the world and the world without agitation.
Let’s fight together and get more tolerance, even if it’s not always easy.

Ralf Semmler

Ralf Semmler

German origin: “the glorious wolf” A sincere human Unstoppable and always ready to find alternative solutions he wants to see results! Often not responsive. He lends life a high sense due its unrestricted efforts.

Where I live we speak swabian. It is in the beautiful south of Germany in Baden-Württemberg, the greater Stuttgart area, on the brink of the Swabian Alb. We are surrounded by different mountains, e. g. the famous Hohenstaufen (known from Barbarossa’s times), the castle Staufeneck, the Rechberg, the Ramsberg etc. The “Filstal” (Valley of the river Fils), which spreads from the east to the west, lies between the mountains. The river “Fils” springs from the so-called “Filsursprung”, flows through our valley and flows into the Neckar.The Neckar winds its way through Stuttgart, passing the largest European companies, such as Märklin, Eberspächer, Mercedes-Benz, Bosch or even Porsche.
