Our People

The Administration Team provides a fast and efficient service.   We ensure that from the point of initial contact to delivery of the valuation, the client’s expectations are met for the agreed fee.

Our key responsibilities are to deliver the valuation within service standards; to ensure valuers provide the information to our team of administrators promptly;  to communicate with clients and introducers about the expected delivery date, making clients aware of any pending delays;  and to supply  the completed valuation documents.

In 2012 Rachel played a major part in a round of investment as part of growing Pall Mall Art Advisors in the UK & European markets working alongside her colleagues in the US under a US Chairman. Unfortunately, due to circumstances beyond Rachel’s control the offices closed in 2016.  Rachel with her team and their love for both the industry and their client relationships wanted to continue, so set up Doerr Valuations where we are today.
