Hans Gonder

1924 - 1961

The company's history began as early as 1924 with the founding of Gebäudereinigung GONDER. Even then, Hans Gonder laid the foundation for a company that would distinguish itself through quality, reliability and customer-specific services. Today, as then, a high standard of service, satisfied customers and employees are of great importance to us at GONDER. This has not changed in almost 100 years of the company’s history.
