Abby Brody
New York, NY
Abby is a lifetime educator with over 15 years of experience in the classroom and 12 years in administration. With MYX, she is leading the charge to present a new approach to higher education that meets the needs of the 21st century by creating experiences for young adults to find their life purpose while also gaining essential skills for life success.
It all started when she founded Mind the Gap, an organization devoted to studying why higher education was failing its students and designing solutions. In her research, Abby began to see that students are not being served by the traditional college track, which often leaves them shackled in debt and without life skills to succeed in the workforce. Coupled with the fact that that the value of higher education with respect to life success has less to do with credits and more to do with experience, the solution became clear.
Abby assembled a team of fellow educators with deep expertise in traditional higher ed, experiential learning, place-based learning and more, then added a dose of real life with coaching and culture experts who could help serve the needs of the whole student as they set out to create their future.
Prior to founding MYX, Abby was a founding member of Avenues: The World School where she held multiple leadership positions, helping develop the first interconnected global independent school.
Abby earned her B.A. at Duke University and her M.S. in special education from Bank Street College.

The family traveled back and forth to MSKCC in NYC from Missouri to be able to see the neuroblastoma specialists and to have access to cutting edge treatments. With the help of the trials that the Band of Parents funded, Rhyan is with us today. The only treatment that cleared her cancer was Hu3f8, which was a trial funded by BOP. Her treatment for her brain relapse, 8H9, was also a trial funded by BOP.
Jen and Brad became very passionate about raising funds for pediatric cancer when they were thrust into the cancer world. They quickly realized how grossly underfunded cancer was on the pediatric level and decided that they needed to do something about it. Between Jen and her husband, they both sit on boards for pediatric cancer organizations and have started their own foundation, RallyforRhyan, which has raised over half a million dollars for pediatric cancer research.
Rhyan has currently been cancer free since November 2016.
