As a young performer, Mark reverently evoked 1940’s nostalgia with the Glenn Miller Orchestra for 9 years—witnessing the worldwide love of the timeless music.

Most recently, Mark has stepped into the symphony world, with his act The Kings of Soul & Swing. Teaming up with Hamilton star and Broadway veteran, Julius Thomas III, the two friends have rocketed through the symphony circuit - serving up Jackson 5 and Tony Bennett, Stevie Wonder mashed up with Duke Ellington to the audiences of the Bay Philharmonic and the Cape Symphony.

With The SECRET AGENTS, Mark AKA“Agent Milan” serves up groove declassified on Disneyland Resort stages, and for this year’s Disney’s Festival of Holidays.

Across L.A., Orange County, and up the West Coast, Mark appears at local haunts like Herb Alpert’s Vibrato Grill Jazz, Campus Jax, Jazzville Palm Springs, and up-and-coming jazz mecca, Libretto in Paso Robles. A guest artist with several big bands, he also performs with his own bands The Eras Big Band, The Mark Kopitzke Quartet, a 1960’s revue The SECRET AGENTS, and partners with other artists like the star-studded Long Beach Municipal Band, Tom Kubis Big Band.
