Kathryn Sievers began violin lessons in the Marshall Islands when she was five years old. She continued playing violin both in the tropics and in her native Massachusetts, where she was a student of Marylou Speaker Churchill at NEC Prep, where she also played and toured with YS and YPO, studied chamber music, and learned music theory. As a senior in high school, she added viola to her musical studies. Ms. Sievers earned an undergraduate degree in English literature from Yale and a master of music degree from Juilliard, furthering her viola studies at the Cleveland Institute of Music. Influential teachers include Robert Vernon, Heidi Castleman, Misha Amory, and Erick Friedman. As a fellow at the New World Symphony Ms. Sievers won the concerto competition and performed the Bartók viola concerto with the orchestra.
After completing her studies she embarked on an active freelance career, including work with the Cleveland Orchestra, the Philadelphia Orchestra, the Detroit Symphony, the Pittsburgh Symphony, the Los Angeles Philharmonic, and the Santa Fe Opera, and in February 2018 she joined the viola section of the Boston Symphony. Prior to becoming a member, Ms. Sievers worked frequently as a substitute musician with the Boston Symphony and was a member of the Portland Symphony Orchestra in Maine. Each summer she can be heard at Strings Music Festival in Steamboat Springs, Colorado.
