Corporate Culture and the Team of DFGE Institute
Dr.-Ing. Thomas Fleissner,

“Our corporate culture and our team are our best assets. This differentiates us from our competitors and ensures that we exceed our customers’ needs while contributing to integrated sustainable development.”
Corporate Culture and Values
- Our goal is to deliver solutions to our clients instead of creating new problems. We want to take work off our clients’ shoulders so they can focus on what really matters: advancing sustainability company-wide.
- We are constantly evolving: new ideas are always welcome! We optimise our internal processes and broaden as well as deepen our offerings in order to always fulfil our customers’ wishes in the best possible way.
- It is crucial for us to deliver high-quality results. That is why we work according to scientific, international standards. In addition, we have an internal quality management system. Our work is based on facts and figures, rather than “greenwashing”.
- Working at DFGE requires flexibility and the ability to multitask. You will deal with clients from several industries and with a variety of issues, as well as handle several projects at the same time. We also work with clients and colleagues from different countries and cultures, so a good level of English is an important requirement.
- At DFGE, everyone is responsible for their tasks; we believe in self-motivation and personal responsibility. This is only possible if you can trust in the strengths of the team: You can always ask your colleagues for advice, who will help you improve and learn.
- We want the work at DFGE to be fun, both the work itself and the interaction within the team. In this sense, we are a kind of “family business” and “friends”.
