CDM Management Team

Cumberland Diversified Metals has been in business since 1985.  Since October 2022, we are majority owned by Slate Capital Group. Alex Newman the previous President and owner, still maintains a seat on the board and a significant equity piece.

The company is currently managed by Michael Greff and Mike Calvey serving in the President and Vice President roles respectfully, as well as Sarah Cook in the role of CFO.  Together the three partners have over 55 years of combined experience at Cumberland.

The key to Cumberland’s long tenured success is the strengthening of existing relationships and the continuation of building new relationships while maximizing our customer’s experience.
