He performed in the CIM orchestras under conductors Carl Topilow, Louis Lane, Jahja Ling, Michael Stern, and Pierre Boulez.
At CIM, Josué received scholarships from the National Endowment for the Arts and The Music Assistance Fund of The NY Philharmonic Orchestra.

In 1994, Casillas was awarded an internship with the Houston Symphony Orchestra, which enabled him to complete his M.M. at Rice University, where he studied with Aralee Dorough (principal flutist, Houston Symphony) and Carol Wincenc (solo concert artist). While in Houston, Casillas also organized his own chamber music group, The Keynote Chamber Players, presenting monthly recitals, some broadcasted on KUHF, Houston’s classical radio station.

He was received with such enthusiasm that he returned in 2007 and 2008 as principal guest artist, and looks forward to continuing the collaboration.
