I am Christoph Kirn. I help people improve their German language skills in Switzerland. I focus on two groups — architects and engineers and people seeking naturalization or a C-permit.

If you have a different need feel free to get in contact with me. You can send an email to this address. We can see if I’m the right person to help you. If not, I can probably refer you forward.
