Samuel Ostroff
Composer, Arranger, Producer

Samuel Ostroff’s compositions reflect a "sensitivity and lyricism beyond his years" (San Francisco Composer's Chamber Orchestra). With diverse influences spanning Joe Hisaishi, Maurice Ravel, and Brad Mehldau, his music incorporates elements of classical music, golden age film scores, jazz, and indie rock.
​​
In 2024, Sam co-composed the score for the Emmy award-winning HBO series "We're Here." He scored a national ad campaign for Shutterfly, Inc., as well as films premiering at festivals like NFFTY, LA Shorts, SXSW, etc. Other projects to which he's contributed music include the HBO series "Swiping America" and Apple documentary "Poached," directed by David Gelb ("Chef's Table").
​​​
Alongside his scoring work, Sam is an active classical music composer. His piece "Latitudes" was composed for and premiered by the ensemble yMusic (Classical Billboard #1 for 43 weeks). Other works include "Allegro for String Quartet" and "Two Landscapes" (winners of the U.S. National Foundation for the Arts' YoungArts competition) and "Caro Son Tua Cosí" premiered by GRAMMY-winning vocalist Hila Plitmann and GRAMMY-nominated guitarist Mak Grgic.
​​
As a producer, arranger, and engineer, Sam has worked with artists across genres, collaborating with artists like Vincent Lima, Snarky Puppy, and Louis Cole.
​​
Sam received his Bachelor's degree from the University of Southern California, where he was mentored by composers including Ted Hearne, Vince Mendoza, and Thomas Newman.
When not writing music, Sam can be found on the climbing wall, in front of his sewing machine, or on the floor playing with his dog, Joy, and his hamster, Mocha.
