Thats what our customers say

The long-standing co-operation with the sales consultant Siers & Collegen has always been very partner-like and goal-oriented. Especially outstanding with the team of Siers & Collegen is the high implementation competence, whether it be by means of the conception of pragmatic sales guide rails, the qualification of managers & staff or the development of the corporate culture. At large, this has helped us deal with our markets more efficiently nowadays.
Frank Koch, Chairman of the Board
GEORGSMARIENHÜTTE HOLDING GMBH

The joint project with Siers & Collegen helped us considerably, not only to obtain a clear picture of the status quo of our corporate culture but also to create clear common (also cross-sectoral) goals and a resulting interaction on this basis which characterizes and simplifies the common daily co-operation. The transparent and, above all, pragmatic approach is of practical benefit for us so as to achieve change and advance it in a focused way.
Thomas Schmidt, Chairman of the Board
ENTEGA Energie GmbH

We have been co-operating with Siers & Collegen for several years. The clear focus on implementation of Siers & Collegen helped us implement our sales concepts on the market optimally. In addition, it was decisive that the managers were developed into implementation multipliers and, thus, promote the change process optimally.
