Staff and Trustees

Our four part-time staff are:

Kate Sebag – Director

Kate’s professional background is in Fairtrade sales and marketing 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. She became Director of BPCG in July 2016.

Kate has volunteered with the horticultural therapy charity Thrive and 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

Cat joined the BPCG staff team in September 2016. She is a professional gardener, art psychotherapist, potter and stained glass maker.  She has an RHS Level 3 Diploma in the Principles and Practices of Horticulture, a Masters in Psychoanalytic Studies and a Post Graduate Diploma in Art Psychotherapy.  She also has a BA in Sculpture. She is licenced to drive buses and is a pretty good fiddle player!

Cat likes to engage people from all walks of life in gardening and she is a strong advocate for the restorative powers of horticulture and the arts. She believes that gardens are full of images and metaphors about living and dynamic processes. Engagement with the living world, our breathing planet, are an enriching experience open to all.


Helen Cherry  – Education Officer

Helen joined the team in July 2017. She has a LKS2 Primary PGCE with science specialism from the University of East Anglia. She is a keen singer and gardener.  Helen is delighted to be taking on the challenge of running BPCG’s education programme for children.


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 nearly thirty years. She believes strongly in the restorative and enriching benefits that green spaces provide in the city. When she gave up full-time work in Facilities and 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.

Beth Barber (co-Chair)

Beth is an experienced environmental educator who combines practical skills with sound botanical knowledge and a firm belief in the educational possibilities created by plants and the natural environment. She is committed to widening access to, and understanding of, the natural world and firmly believes that green space can be used to improve outcomes and build community cohesion for all Londoners regardless of age or background. Beth has been involved with Brockwell park Community Greenhouses since 2011 when she became our first ever member of staff. She joined the Board in October 2015 and currently occupies the role of Co-Chair.

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 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

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.
