Aleeza Meir was raised as a homeschooler and immersed in music from early childhood. After an early start on piano, she began studying organ at the age of ten, performing in concert less than a year later. Among her teachers have been fortepianist Malcolm Bilson, Fernando Laires (President Emeritus, American Liszt Society; Professor Emeritus, Peabody ), Irina Edelstein (Professor, Frankfurt Musikhochschule) and Jonathan Shames (Director, Marrowstone Festival), as well as Pulitzer Prize-winning composer Steven Stucky.

Her career has included performances in a wide variety of venues and capacities, ranging from concerto soloist to continuo player, as well as music festivals in Europe. She placed second in the 1988 Otto B. Schoepfle National Organ Competition at Oberlin, and in the 1998 International Piano Masterclass of Bechyne festival competition in the Czech Republic.

Ms. Meir is the exclusive keyboardist in NYC for John Rutter, appearing regularly with him at Carnegie Hall. Recent performances include Poulenc's Organ Concerto, Kodály's Missa Brevis, Requiems by Duruflé and Fauré, recitals in NYC on the Donnell Library Center series, the Music at Shelter Rock Series, and the Brooklyn Symphony Orchestra's chamber music concert series, as well as the Brooklyn Philharmonic's Music in the Sanctuaries series, and Bob Chilcott's Jubilate under the composer's baton. Ms. Meir is on the artistic staff for the Boys Choir of Harlem and the Allen-Stevenson School, and organist for historic Old First Reformed Church, the oldest congregation in Brooklyn (dating back to 1654).
