Where would I find statistics regarding UH-Downtown students who attend professional schools (i.e. medical and law school).
I am not aware of any publicly available and/or central source to answer your question. I think your best bet would be to contact the specific colleges involved, like College of Science & Technology and College of Humanities and Social Sciences. Look here for their links: http://www.uhd.edu/academic/colleges/
Also, there is a student association for pre-med students. Look for the American Medical Student Association here http://www.uhd.edu/sae/org_info.html
