Arizona (both U of A and ASU) are actually great safeties - merit for stats is fairly predictable, both have strong honors colleges, both are in cities, and warm winters might be appealing for a New Englander.
I agree that an in state public university should be included in a balanced list. I am thinking that this student may wish to keep her state of residence confidential as she identified as a New Englander. I agree with others that BMC and Scripps are not safeties and Wellesley is probably a low reach.
