About Thomas Grinding, Inc.

Glen and Dianne Thomas started their family-owned business in 1969 as Thomas Construction in the state of Illinois. They originally operated a successful asphalt plant and paving operation.

Later in 1992, they entered the rumble strip field and specialized in rumble strip grinding contract work for state and county road departments, as well as other paving contractors.

Glen & Dianne Thomas

They incorporated under the name of Thomas Grinding, Inc. and became so successful in the rumble strip field that the company built a strong reputation as one of the premier rumble strip contractors, and pioneered the industry with 6 new machine patents to date.

They own and operate their own manufacturing facilities in Moore Haven, Florida and sell rumble strip grinding machines, as well as offer training to contractors, municipalities, and other end-users in the industry.

Today Dianne and Glen are now semi-retired and spend their summers as the owner-operators of the Ninilchik 132.6 Cabins and RV Park in Ninilchik, Alaska on the Kenai Penninisula.
