We act to contribute to the well-being of babies and children and to parental peace of mind; we also aim to help individuals suffering from osteoarthritis to continue doing what they love, for as long as possible.

We believe that human well-being cannot be separated from the health of the planet. We want to have a positive impact on the world around us. Although each of us has a role to play, it’s by working together that we’ll meet our goals!
