Frank O’Sullivan is a professional guitarist, composer, and educator based in Montreal. Originally from Ottawa, Frank relocated to Montreal after graduating from the Berklee College of Music in 2012, where he majored in performance and studied with Tomo Fujita, Tim Miller, and Sheryl Bailey.
Shortly after moving to Montreal, Frank became a first-call musician for the RnB/Jazz/HipHop scenes when he joined the Kalmunity Vibe Collective. Maintaining a prolific and diverse career as an instrumentalist, he has performed and recorded with artists such as Malika Tirolien, Dominique Fils-Aimé, Planet Giza, Busty & The Bass, and Kallitechnis, among many others, touring all over North and South America, Europe, Africa, and Asia.

In June of 2024 Frank will have the honour of playing an opening set for Al Di Meola at the Théâtre Maisonneuve, for the Montreal Jazz Festival.
