Nathanael maintains an active performance schedule, with seasonal engagements on both sides of the Atlantic. He has presented a series of recital featuring music of the 20th century in Italy, Turkey, and Cyprus. His performances have also been broadcast on National Public Radio affiliates around the USA, from Buffalo to Hawaii. In 2002, he formed the Strung Out Trio with violinist Beth Schneider, and guitarist Matt Gould. The trio presents its unique repertoire in concerts throughout the United States, in addition to university residencies promoting the development of young composers at Harvard, the University of Florida, and Uludag State Conservatory in Bursa, Turkey. The group's debut CD recording on Meyer Media Records, features two trios by Paul Richards, and has been featured on radio broadcasts throughout the United States.

In a habit of speaking from stage almost as much as he plays, Nathanael derives true joy from the educational act of performing. From 2001 to 2005, he taught applied piano, literature, and pedagogy as a faculty member of the music department at Eastern Mediterranean University on the island of Cyprus. In June of 2004, EMU hosted the 1st Beshparmak International Piano Festival and Competition, of which he was a founding member. The festival seeks to engender a musical dialogue between the war-torn communities of Greek and Turkish Cypriots, and with the international community at large. Additional pedagogical activities encompass the adjudication of local and state MTNA competitions throughout the Midwest. He has also served as a guest artist/clinician for the 2006 Gladys Frisch Harris Piano Festival at Hastings College, and the 2007 New Music Festival at the University of Nebraska–Kearney. Additionally, Nathanael has conducted master classes at the Blue Lake Fine Arts Camp in Michigan, the Summer Piano Institute at the University of Wisconsin–Whitewater, Del Mar College in Corpus Christi Texas, and the University of Wisconsin–Milwaukee.

Nathanael will complete the DMA in piano performance at the University of Kansas in July of 2008. He has taught at the Eastman School of Music, Blue Lake Fine Arts Camp, Hochstein School of Music & Dance, and Lake Country Conservatory. Nathanael holds degrees from the Eastman School of Music in Rochester, New York, and the University of Wisconsin–Whitewater.
