For many years, ACISO's two predecessor companies, Greinwalder & Partner and INLINE Unternehmensberatung, were the leading consulting firms in the fitness and health industry. ACISO also made it to this spot in 2019. We are proud to have come first place in this annual contest, and we shall continue to always give our best in the future.

Elli Kiener, ASS GesundSEINzentrum in Lauchringen

Elli Kiener

“Because my company was about to close in 1998 I decided to go to Inline Management Consulting. This was the best decision I could have made for my fitness club. All the training and the intensive support with the consultants with the consequent implementation was the success of my company.

Unfortunately, however, over the years I was no longer entirely happy with Inline and was preoccupied with the idea of quitting and joining Greinwalder. When the merger of Inline and Greinwalder resulted in ACISO, I was very critical. But my expectations of innovations, implementations and ideas were exceeded. ACISO is the business and marketing expert in our fitness industry who, with professional networks, consulting and ideas, brings my own company and the fitness industry forwards.”

Helmut Wunderlich, AktiVital Halver

Helmut Wunderlich

“When Health Coach was announced, I knew immediately that it would be another pillar to position my company as a health expert. Today people come to us presenting doctor's letters, with the request to make comments or simply to explain in understandable words what the doctor means.

The training as health coaches has paved the way for us to give people answers to questions, and with it we are gradually becoming recognized as health experts and our position is being consolidated. Today, the coach consultation is a fixed component of the support system for members and the coach training is a fixed component for the internal training of employees! Thank you ACISO for creating this opportunity!”

Urs Zumstein, Panthera Fitness Stans

Testimonial from Urs Zumstein

“Thanks to Slim Belly, we can clearly strengthen our positioning as a ladies' gym. Slim Belly has become indispensable for us: On the one hand from an economic point of view. On the other hand, because our female customers are "addicted" to Slim Belly. Whenever they take a break, they start training with Slim Belly again after a short time, because they can feel and see the difference.”
