ALLENTOWN, Pa. – The longtime music director and conductor of The Allentown Symphony Orchestra is planning to step down after more than three decades at the helm.

The Allentown Symphony Association (ASA) announced today that Diane Wittry will conclude her extraordinary 33-year tenure leading the orchestra when she conducts her final concert in the fall of 2027.

Wittry will continue to serve as music director through May 2028, working closely with the board of directors and staff to ensure a smooth and successful artistic leadership transition.

Her tenure will be the longest in the orchestra’s history, surpassing that of Donald Voorhees, who served for 32 years from its founding in 1951 to 1983.

Officials say Wittry leaves a deep and enduring legacy of artistic excellence, innovation, and growth, championing adventurous programming that paired underperformed masterworks with new and contemporary compositions.

Additionally, Wittry expanded the orchestra’s creative reach by integrating lighting, visual design, video, actors, dancers, and vocalists into performances – broadening audience engagement while reimagining the orchestral concert experience.

Reflecting on her decision, Wittry said, “After many years of heartfelt music making, I have decided to retire from my position as music director and conductor of the Allentown Symphony in the spring of 2028. Together, we have built an orchestra of exceptional professional quality, expanded our concert offerings, championed new music, and deepened our partnerships throughout the Lehigh Valley.”

“I am profoundly proud of what we have accomplished and grateful for the unwavering support of the musicians, board, staff, and community. I remain fully committed to working closely with the board during this transition, and I look forward to the inspiring music we will continue to make together in the seasons ahead,” she added.

The ASA Board of Directors says it has begun forming a committee to lead a national search for the orchestra’s next music director and conductor.
