"I was trained at the Central School of Art and the Sir John Cass College School of Art here in London, I graduated and started my own workshop in 1969 specialising in hand made silver and gold pieces. Now with my son George the Company is a second-generation business.
I travel far and wide for my work. We export some 95% of the pieces we make, the majority of which goes to the Arabian Gulf States, where we trawl the long corridors of Royal Palaces tracking down commissions for our team of skilled craftsmen to make.
Awarded the Queen’s Award for Enterprise in International Trade 2006 and
Granted a Royal Warrant as Silversmith & Goldsmith to HRH The Prince of Wales in 2016, the workshop is one of the largest in London.
There are a number of criteria that steer me through my work and I only enjoy designing and making good, if not great, pieces of silver. It is the quality of the work we produce that drives me on and the extraordinary skill and passion of the craft of silversmithing that makes it all worthwhile.
I have always sought to integrate some of the latest technology alongside hand making skills in my workshop hopefully ensuring that our craft continues to flourish."
