Cleveland—Sonnhalter, a marketing communications firm to the professional tradesman in the construction, industrial and MRO markets, moved its headquarters to 1320 Sumner Avenue, Cleveland, Ohio. The move occurred on February 13, 2015.


The leading B2T (business-to-tradesmen) firm moved from its location from Cleveland suburb, Berea, where it has been located since it was founded in 1976, to an approximately 5,000-square-foot downtown location. The unique new location is the Brownell building, a historic building located in Cleveland’s Gateway District. Brownell was originally built in 1883 as a schoolhouse. It is currently on the national historic registry list, awaiting certification.

The agency, which is known for its business-to-tradesman niche and annual tool drive benefiting the Greater Cleveland Habitat for Humanity, formally began operating out of the newly renovated, second-floor suite on Monday, February 16.

“We are thrilled to be in our new location, with a highly visible presence in a thriving area. The new, larger space will accommodate future growth, will be inspirational to the Sonnhalter team, and is more accessible to our client base,” said Matt Sonnhalter, vision architect at Sonnhalter. “Downtown Cleveland is a hub of activity that recently made the New York Times ‘Top places to visit in 2015,’ list, and we are proud to be part of Cleveland’s revitalization.”

The firm’s new address is 1320 Sumner Avenue, Suite 200, Cleveland, Ohio 44115-2851. Visit
