Some reviews

“Mary O’Sullivan scales impressive vocal heights as Berta. It’s a night to remember.”

Berta in Wide Open Opera’s Barber of Seville, The Irish Times 2016

“Mary O’Sullivan’s natural acting is matched by her unforced pure, clean soprano ... she makes the stage her own [and] her Act II solo is one of the highlights of the evening.”

Wide Open Opera’s Barber of Seville, No More Workhorse 2016

“Mary O’Sullivan as the thwarted Berta gave us some spectacular high notes in her Act II aria and virtuosic duet moments with Rosina”

Berta in Wide Open Opera’s Barber of Seville, Bachtrack 2016

“As Malatesta’s sister, feisty actress Norina, Mary O’Sullivan displayed masterful, nightingale-like coloratura with petite, clear tone. Her capricious, no-messing characterisation was ideal for beating the hapless Don into submission after she has tricked him into ‘marrying’ her”

Norina in ETO’s Don Pasquale, Classical Source 2010

“O'Sullivan has a fluent top register that would stand her in good stead in a production that took her character seriously”

Norina in ETO’s Don Pasquale, The Guardian 2010

“Nannetta was wonderfully sung by Mary O’Sullivan, making full use of a delightfully light, sweet voice”

Nannetta in Scottish Opera’s Falstaff, Opera Now 2008

“By far [one of] the most substantial performances [was] the worldly and spirited Susanna by Mary O’Sullivan”
