Deborah Bial, Ed.D.
President & Founder, The Posse Foundation


About Deborah Bial, Ed.D.

Deborah Bial is an expert in the field of higher education administration, college success and leadership development. Her extensive experience in facilitating dialogue related to issues of access, equity and diversity—and in guiding selective colleges and universities towards improved admissions policy—has gained her national recognition in the higher education community in the United States. 

Bial is the president and founder of The Posse Foundation, a leadership development and college success organization that sends teams (Posses) of students from diverse backgrounds to selective colleges and universities.

The Posse Foundation, a national 501(c)(3), is headquartered in New York City. In 2022, its annual budget of $29 million will support student recruitment in over 20 cities and leverage approximately $170 million in leadership scholarships from its 64 partner colleges and universities. Posse currently has over $130 million in assets (which includes an endowment valued at over $90 million). and a 50-person national board. Its 10 local advisory boards include over 100 members. 

Since 1989, The Posse Foundation has identified more than 10,000 Posse Scholars. These young people have won $1.8 billion in leadership scholarships from Posse’s partner colleges and universities and are graduating at a rate of 90 percent. They are active leaders, both on their campuses and in the workforce. 

In 2007, Bial received a prestigious MacArthur “Genius” Fellowship from The John D. and Catherine T. MacArthur Foundation. In 2010, President Obama named Posse as one of 10 nonprofits with which he would share his Nobel Peace Prize money. 

Bial has grown The Posse Foundation from a concept into one of the most comprehensive and important college success and scholarship programs in the United States. Today it supports programs in Atlanta, Boston, Chicago, Houston, Los Angeles, Miami, New York, New Orleans, the San Francisco Bay Area, and Washington, D.C. In 2020, Posse expanded, using a new virtual recruitment and training model to double its outreach. The Foundation has also established many special initiatives such as the Posse STEM Program, the Posse Arts Program and the Posse Veterans Program. By 2025, The Posse Foundation will boast 10,000 alumni throughout the United States. 

Bial earned her master’s and doctoral degrees in education with a focus on higher education administration, planning and social policy from Harvard University. In 1999, she received a $1.9 million grant from the Andrew W. Mellon Foundation for her dissertation work, which focused on the design and assessment of a new college admissions tool that could be used in addition to traditional college admissions measures. 

Bial is a recipient of the Harold W. McGraw Prize in Education and the Anne Roe Award from the Harvard Graduate School of Education. She completed her undergraduate degree at Brandeis University and has 30 honorary doctorates. She is also a member of the Brandeis Board of Trustees and the Xometry Board.
