A tireless researcher and advocate for the effortless singing professional, Mark Joelson Daboll is a performing baritone, music educator, and voice teacher – a capacity for which he has garnered much praise as a master technician. His 21st century teaching skill-set successfully serves the building of all voices.

A member of the voice faculty at University of Toronto’s Faculty of Music, Mark also maintains a private voice studio in Toronto, Canada. He is sought after as a reliable voice-renovator to professional singers in all stages of their careers, and for the development and re-ignition of misdirected voices. He is a teacher with immediate, accessible solutions to reaffirm individual, authentic vocal identity, and maximize vocal and artistic capability at the highest level of performance.

His students have included internationally renowned actors for film and theatre roles, solo and choral singers of all ages, and senior business professionals desiring to improve ease of speech projection and accent reduction. His students have won or placed in national competitions, and have been accepted into numerous professional development programs.

An active performer, most recently in recital, he performs demanding music in the example of what he teaches. His principal teacher/mentor is W. Stephen Smith, author of The Naked Voice, and teacher of many of the world’s elite singers. Mark served as a vocal coach and masterclass teacher for the 2016 Ontario Youth Choir, and at the COC’s Summer Youth Intensive Program in 2013 and 2014. In demand as a personal and engaging adjudicator at music festivals, Mark continues his association with the COC as a popular workshop presenter for the Living Opera Education Program, for both high school groups and Toronto District School Board teachers.

Originally classically trained, Mark is also uniquely certified to teach all vocal styles, including golden-age and contemporary Music Theatre, Broadway belting, Pop-Rock styles, Country, R&B, and Jazz. His primary teacher/mentor influence in this domain is Lisa Popeil (with whom he is certified as a Voiceworks® Associate teacher); other influences include the works and research of Dr. Matthew Edwards (Shenandoah University), and Jeannette LoVetri.

Mark is also the founder/director of Please Judge Me – the innovative web platform for vocal coaching, through which he has been interviewed on a variety of vocal topics on CBC Radio 1, The Global Morning Show, Schompera.com, CTV.ca, City TV’s Breakfast Television, and featured in University of Toronto’s Alumni Magazine.
