Our History

Founded in 1897 with a small power plant on the banks of the Lonza River in Gampel (Valais, Switzerland), Lonza moved to Visp in 1907. The move enabled our business to scale up our operations and drive our success and growth through the Twentieth Century. Today we are a dedicated strategic manufacturing partner to the healthcare industry, working with customers in the pharma, biotech and nutrition markets.
