Senogles & Co, Chartered Accountants was first established in 1925 in Bangor, North Wales by Harold Senogles.  We are approaching our firm’s centenary in 2025…

The firm's focus was originally on accounts preparation and taxation advice to businesses and sole traders across the beautiful Isle of Anglesey (Ynys Môn) and Caernarfonshire areas of North Wales.  Steady progress was made in their offices in Arvonia Buildings, Bangor and the practice grew in terms of clients and staff.  

In 1948, on his return from active service in India and Palestine with the British Army, David Senogles joined the practice as an articled clerk.  Gradually, David took over the running of the practice from his father Harold.  A smooth handover passed the baton from father to son. Our clients always were (and remain) the focus.

In the early 1980s, Senogles & Co relocated from the mainland to Ynys Môn (Isle of Anglesey), into offices in Menai Bridge - right next to the Menai Suspension Bridge (shown below: a view from Ynys Môn of the suspension bridge over the Menai Straits with the Snowdonia mountain range behind).

On the sudden death in 1985 of David Senogles, the family practice was sold to local accountants Cecil Williams Denton & Co; itself a very well established and respected firm in Bangor.  During the early years of this transition, both Geoffrey and his sister Delyth worked in the firm - which now trades as Willams Denton. 

Geoffrey Senogles and his partners have revived the family firm - now located in Nyon near Geneva, Switzerland.  By choice we are still based near water, still in beautiful landscape, and still looking out over a mountain range (below: a view from Nyon across Lac Léman with the French Alps behind).    

Steve Brookfield and Geoff Senogles first met in 1997 when working together in Pannell Kerr Forster, chartered accountants in Liverpool, UK.  Sveta Ksenofontova joined our firm soon after our renaissance, having worked with Geoff in a large American consulting firm. Ellie Senogles joined the firm in September 2021; and so our firm’s history goes on…
