I don't know if you are asking a question, or making a statement?
If you are asking a question, and I assume the question is how this young lady can place herself to be seen by the members of this org, then my advice would be for her to start getting involved in activities where Black women in this org can see her.
Church is always a good place to start.
She should find out the event calendar of this org and attend their events. These activities are usually published in the newspaper's society / social section. And, if she can get to know some of the members of this org, she could volunteer her time to them to be a speaker or panelist for one of their events.
If she's on the board of an art museum, then can she use her influence to coordinate an inner city / urban event for youth? For example, the summer is a great time to have a one day or one week summer camp where inner city kids can come in and learn basic art / drawing skills.
Or, are there AfAm specific community groups that she can join? For example, here in Houston we have the Ensemble Theater, which is one of the oldest theater groups founded, run, and managed by AfAm. They always present plays by AfAm artists and play writers. We also have an AfAm operatic organization called the Houston Ebony Opera Guild. These are just two well know AfAm specific artistic orgs in Houston where one can become a member and in the process get to know women in NPHC sororities.
If you are making a statement, then I think members of her org of interest would find her activities an asset to their chapter.
