Simon has gained a wealth of experience having first come into estate agency with a firm now known as Hamptons International in 1988. He has been a member of the National Association of Estate Agents since 1991 and has always advocated the need for Estate Agents to be part of a professional organisation, which would give the public confidence that they are dealing with competent people in their chosen profession. In fact, he is also a member of ARLA (Association of Residential Letting Agents). He is also proud to be a member of The Guild of Property Professionals, which is invitation only.
