A very special day today at Birmingham Assay Office as the whole team came together to send our warmest wishes to our 14th Assay Master, Doug Henry, on his retirement.

Doug joined Birmingham Assay Office in September 2014 and has led as Assay Master for the past nine years, guiding the organisation through a period of real transformation — not least our major move from Newhall Street to our current, purpose-built home on Moreton Street.

We're delighted that this isn’t goodbye, as Doug will remain part of the team as one of our Guardians.

In a farewell message to the team this morning, Doug reflected:

“We are all custodians of this great organisation and will play our part in its history before handing over to our successors.”

We would like to say a huge thank you to Doug for his contribution to our story.

It was great to catch up with our Guardians today at our AGM ⚓️

While we connect with them individually throughout the year, this was a valuable opportunity to showcase how our services are evolving across the business.

We’re proud to have such an incredible team, bringing energy, expertise, and a genuine passion for our customers.

It was also a special moment to witness the handover of the badge of office from Doug Henry to Roxanne Guest, as she steps into her new role as CEO and Assay Master.
