Hugh Simon, Treasurer

Hugh is a Chartered Management Accountant, having qualified in 1972, when he was appointed a Divisional Management Services Director with Tube Investments.  From 1979 he was finance director of a number of companies, initially in domestic appliance manufacturing, then in telecommunications.  He was Finance Director of PageOne Communications from 1996 until his retirement in 2011. 

Hugh is an enthusiastic amateur gardener, having been instilled in him from an early age by his father, John Simon, who was a landscape gardener and a Chelsea gold medal winner for a formal show garden.  Hugh has lived in Speen near Newbury since 1986.


He joined BGT as Treasurer following his retirement. Hugh leads on all BGT finance matters, insurance and arrangements for our AGMs.

Fiona graduated with a degree in History and then worked at British Telecom for 20 years, doing a variety of roles including procurement and European telecoms policy. 

Early in the new Millenium, early voluntary redundancy at BT allowed Fiona to do a part-time Birkbeck MA in Garden History.  This led to a role as Co-ordinator of a new Arts & Gardens Programme at the Royal Berkshire Hospital. Fiona then worked for four enjoyable years as Education Officer for the Garden Museum next to Lambeth Palace in London.  While there, Fiona attended a range of museum, educational and garden-related events that introduced her to the world of the (then) Garden History Society and the Association of Gardens Trusts (now merged as the Gardens Trust).

At the time, there was not a Gardens Trust in Berkshire, so along with Christina Hill Williams, Ben Viljoen and Liz Ware, Fiona co-founded the Berkshire Gardens Trust in 2009.  She has been a Trustee ever since.   Fiona is Secretary to BGT and leads on our liaison with the Gardens Trust.
