Based in Geneva, Switzerland, Thill Consulting Services is a small environmental engineering consultancy supporting organisations across sustainability, resource management, project delivery, and education.
The consultancy was founded by a PhD-trained engineer with professional experience in Switzerland, the United Kingdom, and Luxembourg. It developed in response to requests for practical support following several years of work at CERN.
We work closely with each client, combining technical knowledge with clear communication and hands-on delivery. When a project requires wider expertise, we can also draw on a network of specialists in Geneva and across Europe.
Small by design, we offer direct involvement, flexible support, and solutions that are realistic to implement.
