More women are entering STEM (science, tech, engineering, math) professions, but they still only represent a fraction of the workforce. For many years, we focused on the end of the pipeline- getting girls interested in STEM in college and high school. But to reach a critical mass, we need to start getting girls interested in STEM at a much younger age in order to cultivate talent.

"Every time a girl drops out of computer science, we're looking at another H1B visa," said Launch Angels chief executive Shereen Shermak, who joined Under the Radar with Callie Crossley this week. "Think about in the bigger picture- why do we have to bring in developers from other places when we could be filling those seats with brilliant girls?"

Callie Crossley spoke with Shermak and Kimberly Bryant, who founded the organization Black Girls Code, on Under the Radar this week about what there is to gain when we engage girls in STEM from the very beginning of their education.
