The vast majority, if not all, of counseling psych PhD programs emphasize multicultural issues and cultural competency. Of the clinical psych PhD programs that have a focus on research that serve ethnic minority populations, I’d look at UCLA, Arizona State University, George Washington University, Catholic University, UNC at Chapel Hill, CUNY, & Loyola University Chicago. Loyola has such a strong focus on diversity, they have specific web pages on faculty that have interests serving marginalized populations. I hope this helps!
