The Plano Symphony Orchestra in Texas has received $410,000 from Tammy and Charles Miller, the largest single donation in the organization’s history. The gift will fund several new initiatives, including $200,000 in funding for four years of the newly created position of assistant conductor, with the audition process for the position to be announced separately; a $50,000 matching-gift challenge for the 2021-22 season; $50,000 in new technology and ticketing system/donor management system upgrades; $50,000 to fund additional strings for orchestra concerts; and $60,000 to underwrite the PSO’s 40th-anniversary season in 2022-23, including sponsoring a concert featuring Mahler’s Symphony No. 2 (“Resurrection”). Hector Guzman, music director of the Plano Symphony Orchestra, will also mark his 40th year leading the orchestra in 2023.
