A violist of international reputation, Roberto Díaz is president and CEO of the Curtis Institute of Music, following in the footsteps of renowned soloist/directors such as Josef Hofmann, Efrem Zimbalist, and Rudolf Serkin.

Ricardo Lorenz, Roberto Sierra, and Jennifer Higdon have all written concerti for Mr. Díaz.
As a frequent recitalist, Mr. Díaz enjoys collaborating with young pianists, bringing a fresh approach to the repertoire and providing invaluable opportunities to artists at the beginnings of their careers. In addition to performing with major string quartets and pianists in chamber music series and festivals worldwide, Mr. Díaz has toured Europe, Asia, and the Americas a member of the Díaz Trio with violinist Andrés Cárdenes and cellist Andrés Díaz.

Since founding Curtis on Tour eight seasons ago, Mr. Díaz has taken the hugely successful program to North and South America, Europe and Asia, performing chamber music side-by-side with Curtis students and other faculty and alumni of the school. His tenure as president of Curtis has also seen the construction of a significant new building which doubled the size of the school’s campus; the introduction of a classical guitar department and new conducting and string quartet programs; the launch of Curtis Summerfest, summer courses open to the public; and the debut of an online stage called Curtis Performs. In the fall of 2013 Curtis became the first classical music conservatory to offer free online classes through Coursera.
Also under Mr. Díaz’s leadership, Curtis has developed lasting collaborations with other music and arts institutions in Philadelphia and throughout the world and established a dynamic social entrepreneurship curriculum, supported by a prestigious Advancement Grant from The Pew Center for Arts and Heritage. Designed to develop the entrepreneurial and advocacy skills of young musicians, this curriculum includes the project-based Community Artist Program (CAP) and post-graduate Curtis ArtistYear Fellowship Program. Curtis was the first higher-education arts institution to join ArtistYear and respond to the challenge issued by the Aspen Institute’s Franklin Project: to foster a 21st-century national service system, with a goal of one million service-year positions created by 2023.
