The associated partners of our group have many years of experience as consultants in the business world, PROCON GmbH, for example, in consulting since 1993. Most of our references are also long-term client relationships that have developed from mutual trust. However, since the work of the consultant and trainer is usually carried out on the client’s sensitive issues, the protection of both data (see our data protection guidelines in the most recently published version) and the nature of the cooperation is a high value to which we feel professionally committed. Therefore, we only show here a representative selection of company names of clients whose cooperation with us dates back at least 3 years. We ask for your understanding for this discretionary measure. We are always happy to provide more detailed information – which, however, is also subject to the highest principle of protection of confidence.
