Shelyak is for us a peculiar star; we studied it during several weeks. It was then natural for us to name our company Shelyak Instruments.
In May 2016, Olivier decided to leave the company. From this date, François COCHARD becomes the only owner and the general manager. François is a mechanical engineer (Arts & Métiers).
We are located in Le Versoud, a small city close to Grenoble, in french Alps.
