"Heather Gallagher as Despina was the standout in the cast...Her seasoning showed in her comedic flair and confidence; Gallagher tossed off her two arias with panache and proved quite hilarious in Despina's masquerades."
-Lawrence A. Johnson, The Miami Herald Review of Cosi fan tutte
"Heather Gallagher, as Charlotte, was a clear highlight of the evening: Gallagher manages a radiant full tone throughout her entire range that is both full and sensitive to the vocal line.”
-Sudeep Agarwala, The Boston Musical Intelligencer, Les letters de Werther
Heather Gallagher made a vivid and convincing character out of the small role of Isolt’s mother …

The production was...particularly well-sung and movingly acted by mezzo-soprano Heather Gallagher.

"Heather Gallagher, as the Marquise, captures her character’s flightiness,pride and, ultimately, shame and mercy..."
-Alex Hanson, Valley News review of The Daughter of the Regiment
"Mezzo-soprano Heather Gallagher was great fun, and an able singer as the haughty but confused Marquise."
-Jim Lowe, The Barre Montpelier Times review of The Daughter of the Regiment
"…The dream aria on her analysts’s couch, so 1950s, was Gallagher’s moment. Her placement on a well-elevated recamier allowed her to project attractive tone in support of enigmatic character."
-Lee Eiseman, Boston Musical Intelligencer, Trouble in Tahiti
"Neither Dinah nor Sam was written to evoke much sympathy—both skipped their kid’s play—and both were stubborn narcissists. But their fencing and feigning were depicted in robust style by Heather Gallager and Joshua Miller."
-Lee Eiseman, Boston Musical Intelligencer, Trouble in Tahiti
"Heather Gallagher’s Dido throughout the evening, was simply fantastic. She believably played the many different facets of her character with ease, including the fetching naivete shown at the first blush of love in the first act, setting us up precariously high for the third act’s great fall. Her lyric mezzo was velvety and rich, presenting the musical line and text in a beautiful clear enunciation that allowed Purcell’s tragic characterization to come through."
- Joseph E. Morgan’s Review of Dido and Aeneas
"The serious mood was first broken by Heather Gallagher’s excellent rendition of “Hotel”(Poulenc). Alternately playful, lounging and languid as she drew chuckles from the audience. "
