Meet our team
People are at the heart of what we do and are integral to deliver our mission. Without our incredibly talented and dedicated team of staff and volunteers, past and present, The Green Estate would not be the impactful and successful organisation it is today.
We are one of the largest social enterprises in South Yorkshire. Our skilled and diverse team is made up of 70 staff, over 40 volunteers and a supportive Board of Directors.
Our values are important to us and core to who we are:
- We are innovative and impactful
- We have integrity
- We care for our local roots
- We are collaborative for common global good

What’s a typical day at The Green Estate?
Short answer is – there isn’t one! With 100+ staff and volunteers, ten products and services across four sectors, plus an international commercial arm, there is a lot of variety and plenty of work to do! My days tend to be a mix of problem solving, supporting the team to flourish, championing the organisation and building strategic partnerships. I also try to take time to enjoy the amazing landscape and heritage facilities cared for by our talented team.

What’s a typical day at The Green Estate?
For Dan, no two days are the same. His role is primarily a blend of client interaction, team meetings and strategic oversight. A typical day might include meeting and advising clients, site visits, collaborating with teams, overseeing and reviewing design plans, research and development, or business planning and administration.

What’s a typical day at The Green Estate?
For me, a key focus is that our teams are empowered and equipped to deliver a high-quality experience for our clients. With the broad range of talented services operating within The Green Estate, it means my days are very varied, but they always involve listening to the direct experiences of my colleagues and problem solving to find a way forward. That can include ensuring we have the right staff in place to deliver training, evidencing our practices and impact to external auditors, or planning our training needs for the road ahead.
