Xentry Systems names new operations director

A division of Miamisburg-based Matrix Systems Holdings has named a new senior director of operations, company officials announced Friday.

Xentry Systems Integration, a security systems service and installation company headquartered in Columbus, has named Mark Ring as senior director of operations.

In this newly promoted role, Ring will be responsible for leading Xentry’s growing field operations in the company’s eight-state territory, officials said.

The move follows this week's appointment of John Nemerofsky as Xentry's president and chief executive.

The Dayton Daily News reported this month that Xentry had acquired Acree Daily Integrated Systems of Columbus. The combined company operates under the Xentry brand and is headquartered in Columbus. Xentry has more than 110 employees in Columbus and at service hubs in Miamisburg, Cincinnati and Cleveland.
