Johan Stellingerwerf - Managing Director Sodexo Altys
You can lose clients while having a high level of client satisfaction. Clients for Life gives the word 'value' a whole new meaning. I now view the relationship from the perspective of what relevant added value you can deliver from your organization rather than from your product or service. This allows me to shape the relationship with my clients in a different way. Very inspiring.
