Brentwood?
“...the school in Valley Village, an area with a large Jewish population in the San Fernando Valley region of L.A.”
Valley Village. It’s over the hill from Hollywood not far from Burbank or Sherman Oaks - the north side of Highway 101 and west of the 170. Not far from Warner Brothers and Universal Studios. Lots of Jewish people in that general vicinity. I grew up not far from there ages 3-12. My next door neighbors were Holocaust survivors, they had their arms tattooed. Extremely nice family and last I heard a few years ago they were both still alive.
