Cornerstone Records Management has acquired Docushred USA, which provides secured document destruction services and has operations in Cheektowaga and the Rochester area.

All of Docushred’s employees will be retained, said Terrance J. Cahill, senior account manager for Cornerstone, which is based in Maryland. “Customers of Docushred will see no changes in their services except that Cornerstone will now be providing those services,” he said in a statement.

Cornerstone already has a presence in Buffalo Niagara. In 2011, Cornerstone completed its acquisition of locally based American Records Management.
