Locating SBR Health at the Cambridge Innovation Center has many advantages, such as ready-made infrastructure, a community of entrepreneurial companies, the Venture Cafe, but today brought an unexpected surprise as a construction crew showed up outside my office to saw a hole in the wall. At first it looked like they were installing a dog door but further investigation revealed they were installing a plexiglass panel to expose the original floor strut that Governal Deval Patrick and MIT President Susan Hockfield helped install when the CIC expanded into the fourth floor space I know occupy. Who knew this was such an historic location?
