With a radiant voice of beauty, power, nuance and musicality, and a demanding stage presence, Lisa Daltirus is poised for a major career in Opera and Concert. The 2002-2003 season marked her professional operatic debut in the title role of Tosca with the New York Grand Opera .

"Imperious, Her Eyes Ablaze, The Very Image of Tosca...she exuded an intangible electricity, that charge that comes across to the audience when something is really happening onstage." The New York Times.

Engagements in the 2004-2005 season for Miss Daltirus included Aida for the Connecticut Opera, followed by her Amsterdam debut as Lia in Debussy’s L’enfant Prodigue under the baton of Valery Gergiev at the Concertgebouw, Rosalinde in Fledermaus in Thessaloniki, Greece, and her Opera Company of Philadelphia debut in the title role of Aida. She continued the season as Tosca for her Michigan Opera Theatre and Carolina Opera debuts, and closed the season as the soprano soloist in Beethoven’s Symphony No. 9 with the Philadelphia Orchestra.

Miss Daltirus opens the 2005-2006 season with her first Leonora in Il trovatore in Hartford, Connecticut, a return to Philadelphia for Margaret Garner, her Palm Beach Opera debut as Tosca, her Minnesota Opera debut as Tosca, and a return to the Michigan Opera Theatre as Aida. Future engagements include her return to the Boston Lyric Opera as Aida, Bess in Detroit, Serena in Porgy and Bess in Philadelphia, Nedda in Nancy, France, Aida at the Cincinnati Opera, and Madame Lidione for the Seattle Opera.

Of Miss Daltirus’ debut as Tosca at Opera Delaware, The Philadelphia Inquirer reported "Dazzling Discovery at Opera Delaware ...the voice heard in the title role was reminiscent of - Leontyne Price.”  The monthly Opera News echoed the praise: "...plainly a star in the making...Leontyne Price is a clear (and welcome) model vocally....Her full, liquid sound illuminated line after line with musical polish and detail and soared impressively on high B-flats and Cs."

The 2003-2004 season included Miss Daltirus return to Opera Delaware in the title role in Aida, her debut at the Opera Theatre of St. Louis as Santuzza in Cavalleria Rusticana, with the Boston Lyric Opera as Tosca, and Verdi’s Messa da Requiem at the Aspen Music Festival under the baton of David Zinman,

Miss Daltirus has been featured by the Bel Canto Lyric Opera of Philadelphia in roles and scenes to include Amelia in Un Ballo in Maschera, Santuzza in Cavalleria Rusticana, and Leonora in La Forza del Destino. She has been featured with the Philadelphia Chamber Chorus in a concert Porgy & Bess, has sung the role of Marguerite in Faust and the title roles of Tosca, Aida and Amelia al Ballo in Menotti's version with the Trinity Opera Theater of Philadelphia. Maine Grand Opera featured her in its inaugural gala which led to an unscheduled “Afternoon of Song” recital, due to the overwhelming audience response. Miss Daltirus made her Carnegie Hall debut with New York Grand Opera singing the title role of Aida in the "Triumphal Scene". Miss Daltirus made a last minute Avery Fisher Hall debut at the Richard Tucker Foundation Gala stepping in for an indisposed Aprile Millo to sing the "Triumphal Scene" from Aida. "Their solution was to pluck from the audience Lisa Daltirus...she acquitted herself very well. In fact it would have been wonderful to hear more of her. Maybe next year." The New York Times.

An active soloist with orchestra, Miss Daltirus debuted Beethoven's Missa Solemnis with the Baltimore Choral Arts Society. She returned to the Philadelphia Chamber Chorus to perform two versions of Dona Nobis Pacem by Vaughn-Williams and Fanshawe (from African Sanctus). She has been heard in Mozart’s Requiem with the Mainline Ecumenical Choir and Symphony. Her recent performance of Poulenc’s Gloria with the Wichita Symphony led to an invitation to perform Samuel Barber's Knoxville Summer of 1915 with the Wisconsin Chamber Orchestra. Other repertoire for Miss Daltirus includes Handel’s Messiah, Mozart’s Vesperae Solemnes; Haydn’s Mass in Time of War, Faure’s Requiem; Mahler's 8th Symphony and the Chichester Psalms.
