The Wallich Board Chair - Will Henson Trustee Chair


The role of trustees in charity governance cannot be underestimated. Our diverse board of experts help The Wallich remain solvent, compliant, safe and trusted.

The third sector is currently facing a number of challenges, with ever increasing demands and resources that don’t increase at the same rate.

As trustees, they are committed to ensuring that services are delivered to maximum public benefit whilst upholding the highest ethical standards.

At The Wallich, we hold our organisational values close to our hearts and they transfer directly into how we set the culture of the charity at board level. Ultimately, our role is to scrutinise but this must be balanced with our supportive role as critical friends.
