Customer reviews


Kees has extensive knowledge of the sterilization validation of medical devices. He also actively contributes to this and comes up with good solutions. Even if the validation route to be followed is less obvious, Kees will come up with the right solution. It is also important that he knows how to translate the information from the various standards into an explanation that is easy to understand for laymen. In short, Kees provides a clear explanation with a pleasant cooperation.

MedInvents N.V.

Mr. Kees Frémery has been a loyal and competent advisor to our company MedInvents for 6 years. One of MedInvents' core tasks is to market the product in sterile packaging. The steam sterilization, validations were co-initiated by Mr. Frémery. Since then, we see each other at least once a year to re-validate the sterilization unit or faster if the production process is adjusted. Each time, the very solid expertise was kindly transferred to the people involved in the process on a daily basis. Even in unexpected circumstances we could count on intense attention so that the problems were always completely resolved in a short time. MedInvents hopes to enjoy its specialized assistance for many years to come.
