As previously mentioned the family makes a huge difference along with the young man's view of himself. My boy who is an attending now graduated med school at 42. He was the only Black male in his class. He went to undergrad, joined a frat, and then had to leave school. He joined the military and it wasn't until he told a Black MD that he dreamed of becoming a doc that this MD worked to convince him he could do it. At 30 he started taking courses and was finally accepted at 37. At my friends MD graduation party his brothers, mother, and father all told me that they doubted he would ever be able to do it. They discouraged him every step of the way. Every test, every visit home, every conversation my friend had to deal with his family's insecurities. This is from a man who was raised in a two-parent home along with his whole friends being from two-parent homes. It's a matter of belief and the more men who ignore the naysayers and go for it, the more we will see, and believe.
I'm a pastor-in-training in a predominantly White denomination. The rest of the denomination marvels how our congregation has had up to 5 interns and all either Hispanic or Black. The reason? A Black pastor. It's no secret.
The more our young Black men see Black MD's the more they will believe. My friend knows this and speaks regularly at schools. Like or not Black men are ambassadors of the profession to Black young men....and sometimes even to a Cuban.
