Art-Grube-WebArt Grube, Vice President, Operations

Art, a retired Senior Master Sergeant, U.S. Air Force, developed his cleaning management skills at another firm before coming to Environment Control in June, 1998 as an Area Manager. It wasn’t very long before he was promoted to Operations Manager. In 2013 he was promoted to Vice President of Operations in recognition of his hard work. It is his job to take care of customers, oversee his staff of operations and area managers and make sure that his nightly cleaning staff performs to required standards.

Art and his wife Arlene own 35 acres of land and are frequent vendors at area farmers’ markets; office staff members routinely enjoy produce and freshly laid eggs.
