She originally joined Teach For America after working with Deloitte, Price Waterhouse Coopers, and the Upper Manhattan Empowerment Zone. Previously, as the CEO of ROADS Charter High Schools, she successfully launched two NYC charter high schools, serving over 400 students facing unique challenges. Her leadership extended to overseeing a nationwide network of all-girls' public schools and a college access program in NYC as the Executive Director at Student Leadership Network.

Throughout her career, she held progressive leadership roles at the New York City Department of Education (NYCDOE), ultimately serving as Chief Operating Officer (COO) in the Office of New Schools.

Jemina's personal journey as an African-American and Puerto Rican woman raised in the South Bronx, overcoming obstacles to graduate from Ivy League schools, profoundly shapes her belief that an excellent education is the greatest lever for success and economic mobility. With a commitment to using her time, talent, and voice to fight for equity and access, she serves as a role model and mentor, especially for young women leaders of color.
