Constanze Dennis (1990-2024)

It is with deep sadness that we announce the passing of Grosvenor’s Managing Director, Constanze Dennis, at the end of December 2024.

Constanze was a greatly valued member of the Grosvenor family and the philatelic community as a whole. Further information will be posted when available and we ask clients for their understanding as we process this sudden loss.
