Kelley’s Favorite Thing: Storytelling

Kelley is the co-creator of the Paige & Paxton Elementary STEM curriculum. While working for signature companies such as American Express and JPMorgan Chase, Kelley led nationally recognized STEM pipeline programs for girls and youth of color as one of the founding team members of the New York Chapter of Black Girls Code. She was also a lead member of the planning team for #YesWeCode youth hackathons, designed to expose middle and high school students to opportunities in computer science.

Rachel O. Williams LinkedIn

Chief Operating Officer, Co Founder and Chief Mom
Rachel’s Favorite Thing: Epiphanies

Rachel Williams is a mother of two millennials, an entrepreneur, a marketing communications expert and a fitness fanatic. She was the “alpha” tester of the Paige & Paxton approach over 20 years ago when she wanted to ensure that her daughters were proficient in math and science. She devised an innovative way to make some of the complicated STEM concepts more interesting. While she didn’t have a STEM background, she was an award-winning marketing communications professional who had more than 20 years of experience in successfully communicating complex ideas to general audiences. She leveraged this skill set as a communicator, journalist, and educator by using two puzzle piece characters to make the complicated concepts more fun and engaging.

Twenty years later, something amazing had occurred. Both daughters were excelling in science and math-related fields and actively involved in STEM pipelining programs for youth. They convinced their mom to bring the puzzle piece characters back to life in the form of an early elementary STEM curriculum. Since then, the trio has been on a mission to engage a new generation in STEM. Rachel’s other passion is personal training. She is a certified personal trainer and adheres to a rigorous workout schedule. Believing that “it’s never too late to look great,” her work focuses on getting older adults excited about fitness. Rachel has a Bachelor of Journalism and a Bachelor of Arts in Spanish from the University of Missouri-Columbia.
