I'm an environment and sustainability consultant and was most recently environmental manager at Castleoak. Here I led the development and implementation of their first environmental and sustainability strategies. I was heavily involved in the design and construction of the first BREEAM Excellent care home in the UK and the first PassivHaus care home in the UK,  as well as project managing business critical work-streams.

I have an extremely broad and deep understanding of sustainability and environmental impacts, life cycle impacts, circular economy issues, government net zero targets and wider other environmental impacts affecting organisations in the UK. 


I believe I am well placed to support and enhance any organisation's desire to improve in this area.
