The only diversity I bring to the table is that I'm a male pursuing my MA to become an SLP. Other than that, I'm a white Irish Catholic in the Northeast. But I have a bit of a different experience having gone to school in the city. While only 10% of the group I've gone through undergrad with was male (5-6 out of about 50-60), there is such a rich representation of ethnicities - Hispanic, African-American, Jewish, Middle Eastern, Asian...you name it. I've been taking Spanish courses because I know how important bilingualism is in this and many other areas, and it's only becoming more important and time goes by.
I guess the sentiment I'm trying to get across is that it's great to see people from so many different walks of life and all different backgrounds pursuing the same goal. I feel lucky that I've gotten to know and work on projects with people who I wouldn't have come across during 12 years of Catholic school, or even my first degree in broadcasting (heavily white-male dominant).
I think the best thing we can do as SLPs to promote diversity is just to be ourselves. Whether it's with regards to sex, skin color, religion, or ethnicity, you never know who will identify with you and say, "Hey, that person looks like me or seems to have a similar background. Maybe I can be an SLP too." That goes for the "stereotypical" white female SLP as well. We can all make a difference, but it should never be determined on our genetics. At the same time, it's those same genetics that may come in handy when establishing rapport and a relationship with our clients, so they're definitely not a detriment!
