Reporting on Two Constituencies?

I need to everyone who has one of our volunteer constituencies (Board, Volunteer, Usher, etc.) AND another constituency (here, Donor or Prospect). How can I pull a list or an extraction that includes multiple constituencies? Everything I'm trying either pulls in anyone who has any one of those constituencies or no one at all. I have confirmed there are plenty of constituents who do fall into this category. 

Thanks for your help! I'm just starting out in this role!
