Michael, Richard and Matthew Polonchak - The Two Rivers Trio

Michael, Richard and Matthew Polonchak - The Two Rivers Trio

Identical twin brothers Michael and Matthew Polonchak began playing violin they were five years old. By age six, they were playing with the D.C. Youth Orchestra Program, and when they were eight, had reached the high-school level orchestra -- then the youngest in that program’s 30 year history. Shortly after, they began playing weddings and recitals with their father, Richard Polonchak and the Two Rivers Trio was born. This “Father & Son(s) trio” has been delighting audiences ever since -- praised for their innovative instrumentation (two violins and a bassoon) and their uncanny togetherness as an ensemble.  Together, they have performed full recitals as visiting artists at Shepherd University, Duquesne University and the Episcopal High School in Washington D.C., have been heard on West Virginia and Maryland Public Radio, and have performed at hundreds of weddings and other special events in the Washington D.C. Metro area.


Michael and Matthew Polonchak are active musicians in the Washington D.C., Baltimore and Philadelphia areas.  Matthew was a full Linehan Scholar for Music at UMBC where he studied recording arts with Alan Wonneberger and Viola with Maria Lambrose. He received a B.A. in Music and Recording Arts and later received a full scholarship to pursue a Masters Degree in Music Performance at the University of Delaware.  In addition to performing with a wide variety of ensembles and artists, he provides classical audio and video recording services for many of the best performers, teaching studios and orchestras in the region.

Michael earned a B.A. in Music Performance from Goucher College, where he is currently a professor of Viola and Chamber Music. He is the former principle Viola of the Loudoun Symphony Orchestra, is a member of the Fairfax Symphony and Tysons-McLean Orchestra, and has performed with many of the region’s finest ensembles including the Washington Concert Opera, the Cathedral Choral Society and The American Pops.  In addition, he has had the privilege of performing in the orchestras of such notable artists as Josh Groban, Evanescence, Cage The Elephant, and the Trans Siberian Orchestra.



Richard Polonchak is the former Principal Bassoonist of The United States Marine Band, “The President’s Own” and The White House Orchestra in Washington, DC and is currently the Applied Professor of Bassoon at Shepherd University in WV where he performs regularly with Shepherd Three Faculty Wind Trio.  He authored “The Primary Handbook for Bassoon”, which is published by Hal Leonard and used in educational institutions throughout the world.
