D & S Realty, Inc., a sizable commercial property owner in the Worcester market, recently purchased 70 Hartwell St. for $2.6 million. Mercantile Image Press had most recently occupied the property prior to closing its doors in 2006. Soon after D & S Realty acquired the property, a lease was negotiated with Columbia Tech and DCI Engineering, both Worcester-based subsidiaries of Coghlin Companies, Inc., a privately held contract manufacturing and engineering services organization. William Kelleher IV and James Umphrey of Kelleher & Sadowsky Associates represented both the buyer and seller in the sale of the building, and also represented Columbia Tech in lease negotiations. The 53,000 s/f manufacturing facility was built in 2000, and is considered one the area's finest manufacturing buildings. The industrial property offers many amenities including Class A office space, air conditioning throughout, humidity control, conference facilities, ample room for expansion, and exceptional highway access to Rtes. 190 and 290 in Worcester.
