Dr. Mogielnicki has been teaching alongside her performing career since her undergraduate studies at Juilliard, where she was one of the few female ear training fellows under the tutelage of Mary Anthony Cox. Since then, she has taught at Juilliard Pre-College, Bronx House School for the Performing Arts, the Third Street Music School Settlement, Bard College Preparatory Division, and most recently joined the faculty of the Rome School for Music, Drama and Art at Catholic University where she teaches voice. In 2019 she founded the inaugural vocal apprentice program at the National Music Festival, where she conducted masterclasses and served as mentor to a select group of vocal apprentices. In the Summer of 2021 she joined the Winter Harbor Music Festival as Artist-Faculty where she serves as performer, mentor and Italian coach to festival participants.

The study of voice is an intimate undertaking; it places both student and teacher in a close, and often somewhat vulnerable relationship whereby both parties work towards creating free and expressive singing. This type of close partnership requires careful listening, thoughtfulness, and focus from the teacher and student alike, with generosity, positivity, and a collaborative spirit as a cornerstone for growth.

I place value on personal integrity, hard work, openness and creativity. This is the essence of my approach with students; emphasizing their personal role in their own development, inspiring the desire to dig deeper and work harder, and lifting them up to think creatively and positively about their journey as artists.

My teaching is informed by extensive work with Alexander Technique (specifically Gwen Ellison, formerly of Yale Drama), Kristin Linklater’s Freeing the Natural Voice, and the Thompson Method of Body Work, as well as my own beloved voice teachers and mentors, including Edith Bers, Diana Soviero, Betsy Bishop and Randall Scarlata.
