Without knowing more about you/what you are looking for, and for all that a stranger’s opinion online is worth, I would vote URichmond. Their health sciences program is well integrated with the health services in Richmond, they have an active relationship with a broad range of international universities (which brings more international students as exchange students, further diversifying the student population), and the reports that I have heard back from international students have been very positive.
My experience of Trinity is not as strong. I know a US student who felt that not being able to keep up economically limited her experience.
At both schools the international student population is strongly Chinese, followed by Indian- that may or may not be an interesting element for you.
Both colleges are about 100 miles from a ‘big’ city (to Washington DC for Richmond, to Boston or NY for Hartford).
