Our team

Our team is best known as the 'PKB family' and like any family, we value each and every person that has joined us.

What makes our team truly special is their ability to connect with and understand our patients and clients. That’s because most of us have either worked in the health or social care sector, supported family or loved ones receiving care and treatment, or experienced being a patient at some point in our lives. 

We find it’s this knowledge and real-life experience that really makes a difference. It not only helps us to understand and empathise with our patients and clients but it also pushes us to innovate everyday, to make healthcare services better for us all.
