I think that she meant DPhiE Diversity. Many of the members of MetroDPhiE Alumnae Association are from Queens College. NYC is diverse so the CUNY (City University of New York) system is diverse. Queens College is a part of the CUNY system. The DPhiE chapter at Queens College is a reflection of that diversity.
A few weeks ago I met the former president of that chapter. Her sister is in MetroDPhiE and is also from that chapter.
