Ulrich Kothe, Sales Manager, Albany Door Systems GmbH: 
"Really good sales coaches who know what they're talking about, can put across their topics in an en-thralling way, and practice what they preach are rare indeed. And that's why I'm so glad to have discov-ered Wirkung Plus. The events we organised with you met all our requirements. I cannot express my appreciation too highly. You've hit the bull's eye."
