"Nothing's going to change," Mulligan said. "We're going to operate exactly like Koehler-Kheel did in every respect."
Mulligan said his company had been discussing the move for the last several months. VM had been looking for an office in Easton to run its local projects. It will occupy the seventh-floor of the the National Building, at 400 Northampton Street.
Koehler was not immediately available for comment Tuesday.
