Welcome to my website 

I am happy that you are visiting my new website. 

For those of you who don't know me ...  

My name is

Dittmar Siebert 

I am married and have 2 children.  

I grew up in a traditional craft business (my
grandfather was a cabinet maker) specializing
in wooden and plastic windows. After finishing
my studies at a college of commerce I then
went back to school to become a cabinet maker.
After a year of community service I then studied
wood technology in Rosenheim, successfully
completing my diploma in 1984. 

Through the years I have accumulated a lot of professional and practical experience particularly in the construction of windows, doors, facades and conservatories. 

I concentrated on these areas as well as staircase construction during my time as a technology transfer consultant at the Holzfachschule Bad Wildungen (Institute of Wood Technology in Bad Wildungen). I was also able to apply my expertise in the fields of CAD / CAM / CNC technology. I wrote several books, professional articles and essays about these fields during this time. The highlight was winning an innovation award for a newly developed window system in 2012.

Since March 2013 I am working as a freelance engineer.

Feel free to inform yourself about the engineering and consulting services offered on this website.
