Our Trustees

Caroline Ames

Caroline Ames joined the Activities Working Group in 2017 and was elected a Trustee the following year.   Passionate about plants and gardens, she was drawn to the Trust’s mission to preserve, enhance and re-create London’s green spaces for the education and enjoyment of all.   The seeds of Caroline’s garden enthusiasm were sown when she worked as a guide at Crathes Castle and its glorious gardens prior to going to University.  Living and working in London enabled her to explore and enjoy its many parks and gardens.  
Caroline had a successful career in horseracing administration before establishing a property consultancy with her husband.  She is a keen amateur photographer, especially of plants and gardens.  She is delighted to combine her business and Committee experience in her work for the Trust.
