A clear objective, a joint signature.

Since the company founding, Wirthwein Medical has stood for an open, future-oriented family company with innovation strength and consistent quality orientation. It is our clear objective, jointly with our more than 330 employees, to continue on this path and to establish ourselves in the next ten years as quality leader for highly complex clean room products in the global market.  Thus, we are following the example of the company founder, Fritz Albert Riegler, who laid the foundation more than 75 years ago with a lot of entrepreneurial courage and world view for our company success today.
