Hailed for their outstanding musicianship, the Arianna String Quartet has firmly established itself as one of America's finest chamber ensembles. Their performances have been praised for "tonal warmth, fastidious balance...expressive vitality" (Chicago Tribune) and "emotional commitment and fluent virtuosity," (Pretoria News, South Africa). Formed in 1992, the ASQ garnered national attention by winning the Grand Prize in the Fischoff Chamber Music Competition, First Prize in both the Coleman and Carmel Chamber Music Competitions, and were Laureates in the Bordeaux International String Quartet Competition.

Sought after for their highly effective approach to coaching and teaching as a quartet, the Arianna String Quartet has led the design and implementation of numerous chamber music programs including the Britt Quartet Academy and the FEMUSC Intensive Chamber Music Program in Brazil. In August 2013,  the ASQ and University of Western Cape launched the Chamber Music Institute in South Africa. The institute focuses on ideas of community, outreach and entrepreneurship, and helping students develop skills for a self-sustaining business that gives back to their communities through teaching and performances.

The Arianna Quartet, full-time University of MO-St.Louis faculty, is also Ensemble-in-Residence at the Touhill Performing Arts Center in St. Louis, where they present their own series of concerts.
