Past orchestral engagements include the Minnesota Orchestra, New World Symphony, and Duluth-Superior Symphony. He was featured on the JOYA! chamber music series in 2014 and 2015, the Cedar Valley Chamber Music Festival in 2016 and 2017, and has been a guest soloist for clarinet events at Simpson College, Wartburg College, the University of Northern Iowa, Central College, Iowa State University, and the University of Memphis.

The soprano chalumeau Daniel plays today was produced in 2017 by Polish maker Grzegorz Tomaszewicz. It is based on an authentic tenor chalumeau by J. C. Denner (1655-1707) that is part of Munich's Bayerisches Nationalmuseum collection.
