Staff and Trustees

Our four part-time staff are:

Kate Sebag – Director

Kate’s professional background is in sales and marketing, and overseas development work but she is also a keen amateur gardener.

Kate has been a garden volunteer with BPCG since Spring 2013. As well as gardening, she also developed our events programme and sales of plants and produce.

Kate previously volunteered with the horticultural therapy charity Thrive and has studied RHS level 2 in Horticulture at Capel Manor.

Kate loves working in Brockwell Park which has been her local park since 1986.


Cat Stevens – Community Gardener

Photo and biography coming!

Shayna Soong  – Education Officer

Shayna is a very experienced Environmental Educator having worked for many years with the London Wetland Centre, as well as the Natural History Museum and Eco-Active.  Shayna works at BPCG as our Education Officer, Monday to Wednesday on our kids and young people’s programme.

 Catherine Graham – Education Assistant.

Catherine joined the staff team as Education Assistant in September 2015. She first joined the Greenhouses as an Education Volunteer back in March 2013, as a way to get back into work after having her 5 children. As a result she found a job as a school gardener in Coulsdon and has recently taken on a role as Project Officer for the Croydon Master Gardener programme. She also volunteers with a number of other community growing projects and has a particular interest in horticultural therapy.

Our Trustees are:

Antonia Gross (co-Chair)

Antonia has lived in Lambeth and enjoyed using Brockwell Park as her ‘back garden’ for almost thirty years. She believes strongly in the restorative and enriching benefits that green spaces provide in the city and the transformative effects of horticulture on its inhabitants.

When she gave up full-time work in Facilities and Site Management in 2012, she was keen to ‘give back’ with hands-on involvement in the park and so joined BPCG (as well as Friends of Brockwell Park and The Conservation Trust)

The fundamentals of building management are surprisingly relevant to horticulture – good planning, proper preparation and sympathetic design, all with a healthy helping of pragmatism and adaptability – Antonia is no gardening expert but enjoys volunteering in all areas of the site, particularly the perennial planting. She is our keenest dead-header!

Antonia became a Trustee in 2014.

Martin Lewis

Martin’s professional experience was gained in senior management in London local government. With over 20 years’ experience he has a broad understanding of, and relationships with, the public sector, health and social care and the voluntary and community sectors. He has also worked as Head of Policy for a national think tank providing leadership for local government. Martin is currently a non-executive director of a south London healthcare provider and works part time as office manager for a London MP.

Martin served as the Chair of the Board of Trustees from December 2011 to Septeber 2015, helping the Charity to grow and develop to become a thriving hub of volunteer-led work to promote education, inclusion and personal development through horticulture and the unique nature of the greenhouses.

Derek Hoare (Treasurer)

Derek was instrumental in the creation of the Community Greenhouses and he has been involved in the project since its inception. He is a successful local businessman and combines extensive experience in business, management, finance and employment with a range of volunteering commitments for local organisations. He is passionate about local parks, in particular his beloved Brockwell Park, and he is an active member of both the Friends of Brockwell Park and the Brockwell Park Management Advisory Committee (BPMAC). Derek also founded Lambeth Parks and Greenspaces Forum and chaired that body from 2002-08.

In the past year as a Trustee Derek has been actively working to:
Strengthen the Board of Trustees with a greater range of skills and clearly defined areas of responsibility
Sharpen our strategic objectives and practical programs
Tighten our working structures, administration and communication

In particular, as Treasurer and the Trustee responsible for finance and governance, he has been leading the overhaul of our accounting systems producing monthly management accounts reporting to Trustees.

Linsey MacDonald (Secretary)

Linsey became a trustee in March 2013 and took over the role of Secretary on 13 March 2013.  A solicitor for 18 years, Linsey works at a City firm and deals with commercial disputes.  She is a lifelong gardener with a love of the outdoors and a keen interest in the educational and social benefits which horticulture has the potential to bring to all sections of the local community.



 Katie Styles

Katie has been involved the voluntary sector for over ten years.  Her professional experience is in fundraising, particularly from the public sector and charitable trusts.  She has raised money for a range of different charities and is currently working for a large national youth organisation.

Katie got involved with the Community Greenhouses at the end of 2012 after joining a few Brockwell Park work days and deciding she wanted to get more heavily involved in her fantastic local green space.  Her passion lies in environmental sustainability and she is a novice gardener.

Chris Smith


Chris has been gardening for 40 years and his horticultural interests have been many and varied over that time. An adventurous gardener by nature, he was converted to exotics in 1993 by Christopher Lloyd and been growing Cannas, Bananas and Gingers ever since. He’s interested in ornamentals and rhizomatous plants as well as exotic medicinal and culinary herbs and vegetative propagation and supports the Community Gardener’s volunteering activities in these areas in the greenhouses and around the garden.

He is the Charity’s webmaster, a member of the management team and volunteer development group and serves on the board of trustees chairing its Marketing and Site Management action groups and is an active supporter of our plan to build an Education Centre.
