Recent guest conducting and play-direct debuts which led to immediate re-invitations and significant future debuts include collaborations with Mozarteumorchester Salzburg and Camerata Salzburg, Orchestre National Bordeaux Aquitaine, Orchestre national d’Île-de-France, Orquesta Sinfónica de Galicia, Luxembourg Philharmonic, Lahti Symphony, Verbier Festival Junior Orchestra, Hong Kong Philharmonic, Music in PyeongChang, and Orchestra Ensemble Kanazawa among many others.

Roberto began his career as a solo violinist and a leader and as such collaborates with the Mahler Chamber Orchestra and Berlin Baroque Soloists appearing in Salzburg, Grafenegg, Lucerne, Verbier and Lockenhaus Festivals. Roberto frequently collaborates with singers and instrumentalists including Ian Bostridge, Yuja Wang, Janine Jansen, Alexander Lonquich, Lisa Batiashvili, Fazil Say, Reinhard Goebel, Thomas Quasthoff, András Schiff and Kit Armstrong.

Passionate and dedicated to education and nurturing new generations of talented musicians, Roberto co-founded Iberacademy (Ibero-American Orchestral Academy) together with conductor Alejandro Posada. This institution aims at creating an efficient and sustainable model of musical education in Latin America, focusing on vulnerable segments of the population and supporting highly talented young musicians. While based in Medellín (Colombia), it also operates in Bolivia, Perú, Chile and Cuba, providing its students with life-changing opportunities. Most recently Roberto embarked on a European tour with the Iberacademy Orchestra and star tenor Rolando Villazón, with concerts at the Lucerne Easter Festival and the Mozarteum Stiftung in Salzburg. Roberto also serves as a violin professor at the Guildhall School of Music & Drama and regularly mentors and conducts the Guildhall School Chamber and Symphony Orchestras at the Barbican Hall in London.

With an impressively eclectic and wide-ranging repertoire, Roberto’s variety of styles and interests is also displayed in his recent recording debut featuring Serenades by W. A. Mozart and Othmar Schoeck, released on Claves Records. Gramophone Magazine wrote: In all its 64 minutes’ worth of music, saved from outstaying its welcome by Mozart’s ever-questing ear for an effect, among the most piquant perhaps being the pizzicato passage towards the end of the Andante. It’s played admirably here, under the direction of the well-traveled Roberto González-Monjas. A frequent collaborator of Berlin Baroque Soloists, Roberto contributed as a soloist to their Sony Classical release of Bach’s Brandenburg Concerti conducted by Reinhard Goebel.

Roberto served as concertmaster of the Orchestra dell’Accademia Nazionale di Santa Cecilia for six years and as the leader of the Musikkollegium Winterthur until summer 2021. He plays a 1710 Giuseppe Guarnieri ‘filius Andreae’ violin kindly loaned to him by five Winterthur families and the Rychenberg Stiftung.
