Park and Smith, a financial planning company based in Lakeview, has opened a branch office in downtown Salem in the building owned by the Salem Office Properties real estate company. Park and Smith is taking over office space formerly occupied by the law officers of James Robertson. The space had been vacant for a year and a half. The new Park and Smith office was open for business as of yesterday. Greta Park, president of Park and Smith, says that her company chose the Salem location because of a rising demand for financial planning services in the area. "Salem is a growing community," she explained, "and the town's citizens are becoming more affluent. It is just the type of community where services such as ours are needed."Park and Smith closed its branch offices in Johnstown and Freeburg at the end of the last year. These communities are close enough to Lakeview to be served by the main office there, Ms.Park explained, but having an office inSalem will facilitated expanding services to the entire eastern part of the state. The branch's opening comes just a few months after the opening of the PD Miller stock brokerage firm at the Salem Center office complex.
