“Bernadette Horgan, director of public relations for the Boston Symphony Orchestra and as such a member of the BSO senior management team, is stepping down from her position as of January 20,” writes Susan Elliott in Monday’s (1/9) Musical America (subscription required). “She has been with the orchestra for 35 years, or, as described in an internal memo to staff, a quarter of its existence…. ‘Through both great and challenging times, she has played a critical role in the continued success of the organization …’ reads the memo…. Horgan is the third key executive to step down in as many weeks, following the resignation of Gail Samuel as president and CEO, and Asadour Santourian as VP of the Tanglewood Music Center. Horgan will stay on in a consulting capacity through April. In addition to promoting the BSO’s vast palette of programming in Symphony Hall and Tanglewood, Horgan has overseen coverage of milestone openings … at Tanglewood, as well the centennial of Symphony Hall in 2000 and countless international tours. Music directors of the BSO/pops conductors during her tenure include Seiji Ozawa, John Williams, Keith Lockhart, [James Levine,] and Andris Nelsons. [Horgan] first came to Boston to study with BSO then-flutist Fenwick Smith at the Boston Conservatory.”
