My chapter is very diverse and the girls that we have are so welcoming. That's the first thing that I thought of when I went through recruitment was how open, welcoming, and friendly the girls were. I couldn't see ANY of my sisters turning a girl away because of her ethnicity. Though I've never been to the chapter you're talking about since I am from Michigan, I can't imagine they are any different from my chapter in that respect.
Good luck with recruitment (if you decide to go through) and please keep us updated!
