Danila has a strong background in Human Resources and has worked across a wide variety of sectors in senior HR roles, including Banking, Telecoms, University and Schools. She has always been motivated by making a positive impact on people’s lives and the planet and can’t resist growing plants and visiting green spaces.

Inger Larsen

Community Gardening Training Coordinator

Inger joined Sustainable Merton in the summer of 2021 and is very happy to be involved with their Community Gardens. With a degree in ‘Management of Natural Recourses’ from the ‘Norwegian University of Life Sciences’ and working as a part-time teaching assistant in a secondary school, she is very keen on everything that grows and how we can thrive and grow together in a sustainable way.

Two of her favourite activities are spending time at her local allotment and riding her bicycle.


Helen Rountree

Community Fridge Coordinator

Helen started with Sustainable Merton as a volunteer at Phipps Bridge Community Garden digging and growing fruit and veg. She followed the surplus produce to where it was being distributed at Merton's Community Fridge and offered to help out there... 2 years later she's very proud to be involved in the volunteer side with the people who make the project possible. 


An English language teacher by training, Helen has been lucky to have the opportunity to work in beautiful places such as Mongolia, Iraq, Kazakhstan, Cambodia, Indonesia, Poland and most recently Bangladesh. Now back on home soil and staying put for a while (but still planning some home-based adventures!) she's keen to put the skills she's learnt from her teaching career to good use saving food and giving it to people who need it at The Fridge. 


Helen loves knitting, cooking, running and of course, travelling, helped by the greatest love in her life... her VW campervan "Bendy".
