Leder Masterclasses

Founded in 2020 and made possible by a generous donation from the estate of Geraldine Leder, this 90-minute master class series gives PACO student musicians an exceptional opportunity to work with outstanding professional string players and teachers from around the world.

Past sessions have included individual student musicians working with a masterclass professional and our new format is a professional musician working with our student chamber music ensembles. 

Next Class: Robin Sharp, violin - March 10, 2024.

From Panama to Perth, the JST continued to engage in a comprehensive schedule of learning, performing, and mentoring well into Ms. Kadarauch's tenure with the San Francisco Symphony.

She has given masterclasses at the Colburn School of Music, the San Francisco Conservatory of Music, and the University of Northern Iowa. Most recently Kadarauch was a guest artist-in-residence at the University of Nevada-Reno in 2021 as well as a guest artist for the University of Central Florida in Orlando.

    Kadarauch holds both a Bachelors of Music and Graduate degree from the New England Conservatory, and a Professional Studies Certificate from the Colburn School of Music. Her primary solo and chamber music teachers include Kim Kashkashian, Paul Coletti, and the Cavani and Tackas String Quartets. Prior to her current orchestral appointment, Kadarauch recorded many film scores in Los Angeles, was a substitute violist for the LA Philharmonic, and performed Mahler 7 as the Guest Principal Viola with the San Francisco Symphony while still a graduate student.

    In the summers, Kadarauch can be heard with the Classical Tahoe Festival in Nevada performing symphonic, opera, and chamber music repertoire with colleagues from the Metropolitan Opera Orchestra, the Toronto Symphony, and the Seattle Symphony. She is currently featured on the “San Francisco Symphony Plus” performances of Indian and Zimbabwean music, streaming online worldwide.
