Months after losing its executive director to Pittsburgh, the New Jersey Symphony Orchestra has plucked its next chief executive from Pennsylvania’s other major city. 40-year-old Simon Woods, currently the artistic operations manager of the Philadelphia Orchestra, will take over the business operations of the NJSO in March. The announcement completes the transition to a new management team in Newark, where the NJSO recently announced the appointment of Neeme Järvi as its next music director.
