I work mainly in my home office in Müllheim located in Southern Baden, on customers' sites as needed and in a shared office in Freiburg on a regular basis. You can reach me via the following contact details.


Please understand that I am not always available right away. Sometimes I focus completely on my clients. Just write me a short e-mail or leave a message on my voicemail. I will get back to you as soon as possible.
