Leah graduated from the Masters and Artist Diploma programs at University of Cincinnati, College-Conservatory of Music and she performed many works there, including: Mezzo Soloist in Mahler's Das Lied von der Erde and Symphony No.

Heater has been seen and heard in Verdi's Requiem with Chautauqua Symphony Orchestra in which her 'sonorous yet vigorous phrasing stood out' (Chautauquan Daily), and as Gertrude in Opera Ithaca's Hamlet, in which her 'passion, carnality, and splendid voice completed communicated the transgressions of sovereigns.' () Her first role with Pittsburgh Opera was the role of Cecelia in Little Women in which she “displayed singing and acting abilities that lifted a secondary character into considerable prominence” (Pittsburgh In The Round). She portrayed the title role in Riccardo Primo, Marcellina in Le nozze di Figaro, and Jessie Castner in the Long Walk. Mezzo-Soprano Leah Heater just finished the Resident Artist Program with Pittsburgh Opera, where she sang the roles of Flora in La Traviata and The Page in Salome, in which she “impressed” with her “solid low register” (Pittsburgh Post-Gazette).
