Corralitas Red Car Properties explains that, 

Monte Sano was California's first osteopathic hospital, built in 1923 and closed sometime in the 1970s. According to The Merger M.D.s & D.O.s in Early California, Monte Sano was "envisioned as the perfect recuperation resort on its hill of health."

It was located at 2834 Glendale Blvd. (at Waverly), Silver Lake.

I have no information on this photo yet other than it was identified [at the center-right of the photo] as the Monte Sano Hospital in Glendale.
