US News did an HPM-focused ranking a couple years ago, although most of the programs they ranked are within public affairs / public policy schools, not schools of public health, and they specifically mention masters programs. But, given the interdisciplinary nature of most HPM programs, I think looking at the two rankings lists should provide a pretty decent picture of which schools are among the strongest for HPM (with the usual caveat that U.S. News rankings, or any rankings, should be taken with a grain of salt, etc etc.)
