John Masko

I am an orchestra conductor. I serve as music director of the Brockton Symphony Orchestra in Brockton, MA, principal conductor at the Boston New Music Initiative, and as a cover conductor with the San Francisco Symphony Orchestra. I am currently working to start a new professional orchestra for the Upper Valley. From 2023-2025, I was director of orchestras and lecturer in conducting at Marywood University. I did my Master’s in conducting at San Francisco Conservatory and my undergrad at Yale.

Five Great Symphonies (Winter Term 2026)

Participant Testimonials:

John magnificently took apart the five symphonic works, explained them and explained the symphony in the context of its time.

 One of the best lecturers we have had in OSHER courses.   Was amazed by breadth and simultaneous use of knowledge required of a symphony conductor.

Maestro Masko is MAGNIFIQUE!!!  I’ve taken many Osher courses over the years and I enjoyed this one the most!
