Case Studies

If the past few years have taught us anything, it is that a key quality of any successful organisation is its ability to adapt swiftly and positively to an ever-changing operational environment. Penleaf applauds the high technology businesses, innovators and charities we have worked with recently, which have shown both creativity and resilience during and now coming out of the COVID-19 pandemic.

What we do

Katie Parker, Community Partnerships Manager, Gloucestershire Care Services NHS Trust

'Jenny brings great insight and clarity to any project or programme she is working on. She is able to engage and collaborate across organisations and systems, and lead with clear values and integrity. An articulate communicator and a valued colleague, Jenny brings depth, knowledge, experience and most importantly compassion and humanity to everything she does.’

Peter Maynard, Practice Business Manager, Horfield Health Centre, Bristol

‘Jenny has the rare skill of being able to distil down difficult and complex matters into logical and succinct reports, so that I always feel I have enough information to allow me to question, debate and decide what to do. The fact she does all the above with good humour and grace is just the icing on the cake.’

Peter Gibbons Chief Security Officer, Network Rail

The ethics and values Graham brought to Network Rail represented a clear change to a more compassionate and engaged senior team, which really helped me develop our capability in my particular area of the business.

Siobahn Ritchie, Resourcing Business Partner, Network Rail

Graham is one of the most collaborative, authentic, approachable, and inspiring leaders I have met. I am grateful that I had the chance to work with him.

General Counsel

I have huge respect and admiration for Graham. Definitely the first time in my 12 years I found an exec to be completely approachable and treat everyone the same.
