Critics both at home and abroad have enthusiastically reviewed Maestro Koshak. A Los Angeles Times reviewer wrote: "Carefully regulating each crescendo, Koshak made every climax powerful, dramatic and exhilarating without exhausting his resources at the first fortissimo." In Germany, the Rhein Zeitung reviewer wrote: "both the overall harmonic picture and the artistic discipline can be attributed to the conductor, John Koshak." Of the Brahms Symphony No. 1, the critic described Koshak as a "true Salzburgian." While in Australia, the Sydney Herald music critic wrote: "John Koshak presided over first rate string sounds in the Barber Adagio, and in a Gabrielli Canzona made the brass ring out triumphantly, while Bernstein's Candide Overture hustled along with irresistible panache." About Maestro Koshak's Celebration/Finale Concert with the OCYSO, Timothy Mangan, from the Orange County Register, wrote, "A medley from West Side Story, followed, the orchestra showing a fine sense of its brash and sentimental style, and judging the instrumental balances well, Koshak led them in precise but expressive motions, giving them just what they needed for accuracy's sake without fuss, but also gently shaping the musical flow."
Koshak has conducted orchestras in Australia, China and Europe, and has conducted honor, festival and all-state orchestras in California, Nevada, Montana, Washington, and New York. He has served as artist-in-residence and guest conductor at the Sydney (Australia) Conservatorium of Music and was twice invited as guest conductor of the Pan Pacific Music Festival in Australia.
