Marny Sumrall

Chief Executive Officer

Marny Sumrall currently serves as the Chief Executive Officer of Wishbone, a nonprofit organization dedicated to sending low-income students to high-quality summer programs. During her career, Marny has held various executive roles in the education space, with a focus on promoting student agency and supporting students to become successful learners through innovative, technology-enabled learning environments. In her 17 years with SCORE! Educational Centers at Kaplan, she was responsible for expanding a $30 million division and played a key role in growing the company to $80 million in revenue. During her tenure, Marny led the opening of 75 innovative tutoring locations in five major metropolitan markets with over 400,000 students and families served. She then became Executive Director of YouthTruth Student Survey, a national education nonprofit designed to harness student perceptions to help educators accelerate improvements in their K–12 schools and classrooms. Most recently at AltSchool, Marny managed operations and designed for eight lab schools in San Francisco, Palo Alto, and New York City. At Stanford University, she earned her Bachelor of Arts with Honors in American Studies and a Certificate in Policy for Children, Youth, and Families.

As a high schooler, Marny was deeply influenced by participating in California Girls State, a summer leadership program designed to increase knowledge of governmental processes and citizenship. This experience shaped her commitment to social entrepreneurship, offered her the chance to make friends with young women from all over the state, and exposed her to life on a college campus. She is thrilled to lead Wishbone’s efforts to offer transformational summer experiences for thousands of students across the nation.
