An American clarinetist living in Mexico, has been principal clarinet of Mexico's National Symphony Orchestra (OSN) since 1990 and has played with that orchestra throughout Mexico and in important concert halls in Europe and the United States. She can be heard on numerous recordings by the OSN, as well as those by Camerata de las Américas.

As soloist, she recently gave the premiere of the Clarinet Concerto by Eugenio Toussaint, commissioned for her by the OSN. Ms. Weingartner also recorded this jazz-inspired work by Mexico's preeminent jazz pianist and composer together with two other concertos: one neoclassical, by Argentinian composer, Eduardo Alonso-Crespo, and the other, a charming showpiece by American composer, Charles Fitts. The cd is aptly titled, 21st Century Lyrical Clarinet Concertos.

By way of contrast, Ms. Weingartner has also recorded the Triple Concerto by the French classical composer, Xavier Lefevre, with Miguel Salazar, oboe, Petr Tourkin, bassoon and the Filarmónica de Querétero, conducted by José Guadalupe Flores. As soloist, she has often performed with the OSN as well as with other Mexican symphony orchestras, among them, the Mozart-Haydn Festival Orchestra, the Bellas Artes Chamber Orchestra and the Filarmónica de Querétaro.

Her enthusiasm for chamber music has led Ms. Weingartner to collaborate in a number of recordings of distinction. With the Arianna String Quartet, she recorded the Mozart and Brahms clarinet quintets; with soprano, Jessica Rivera and pianist, L. Mark Carver, she recorded a disc of music for soprano, clarinet and piano, with works by Schubert and Spohr as well as newer compositions by Golijov, Krouse and Salazar. Chamber Music Magazine called this CD " ...a delight from start to finish, and a rate achievement."

As a member of the contemporary ensemble, Trio Neos (clarinet, bassoon, piano) from 1992 to 2004, and as founding member of Sinfonietta Ventus (wind octet), Ms. Weingartner has recorded six cds, spanning from 18th century Harmoniemusik to French works by Poulenc, Milhaud and Bozza, to new commissions by renowned Mexican composers, Mario Lavista, Eugenio Toussaint, Samuel Zyman and Javier Torres among others. With these groups, she has toured in Mexico, the US, Canada, Latin America, Russia and Europe.

Ms. Weingartner studied at Oberlin Conservatory and received her masters degree from Northwestern University with Robert Marcellus. Among her other teachers were Clark Brody, Guy Deplus, and Kal Opperman. She is the clarinet teacher at Mexico's national training orchestra and music school, Orquesta - Escuela Carlos Chavez, where her students have won national and international competitions and hold professional positions throughout Mexico.
