Diamond Cos. takes on new name as part of merger

The Memphis, Tenn.-based holding company of truck dealer and repair shop Diamond International of Springfield has taken on a new name as part of a merger it completed in January.

The merger with Amarillo, Texas-based Roberts Trucks Center LLC resulted in a combined company called Summit Holdings, which will do business as Summit Truck Group, Summit Bus and Summit Lease & Rental, according to a news release.

The company's local shop is now known as Summit Truck Group Springfield, said Mary Dolan of Affiliated Marketing Partners, which was hired to perform public relations functions for the combined company.

She said the Springfield company will undergo signage changes, but she was unsure of a timeline. Steve Cook, vice president and general manger of the local shop, could not be reached for comment by deadline.

The combined company operates 29 commercial truck and bus dealerships in Missouri and six other states, employs 1,300 and expected annual revenue of $1 billion, according to the release.

“We are a new company with a proud 72-year combined history of serving the commercial truck and bus industries. Our new name embodies the strong reputation we have built in the markets we serve," said Summit partner Richard Sweebe, former president of Diamond Cos., in the release.
