At 4.4 GPA and 33 ACT, she has a lot of choices across the US. I suggest not limiting herself to Boston or North East. A lot of students come up with a short list of colleges on their own based on the particular major e.g. Electrical Engineering, Computer Science, Accounting, Business etc. they pick, their desired location to work after graduation, rigor of the coursework, and reputation of the college itself. She will need to do some homework and leg work herself by doing own analysis on the websites such as usnews.com, Princeton Review, and the individual webpages of the colleges or universities of her interest. Many people also do college tour to get a first hand feel for what the college is like. 

The family background and income could also play a role. Certain private colleges give a free ride if admitted when the family income is below a threshold. Public Universities of home state give an advantage in terms of tuition being in-state which could be less than half of the tuition at other state's public colleges or one third or even one fourth of tuition of private colleges. I think it would be a better idea to consult with her other classmates and school advisor than seeking generic and random advice on the web discussion boards.

She will also have to understand that admission application process is really competitive. Admission to highly selective colleges is not guaranteed regardless of the GPA or test scores. But in general if she is interested in Engineering, it would not hurt to aim for colleges like Cornell, Purdue, Washington University of St Louis, University of Texas at Austin while still keeping 3 or 4 safe bet colleges as alternatives. Just my two cents.
