Our Origin Story
Our Executive Director, Greg Lippman, co-founded the 1st charter school in Silicon Valley.
ACE’s Founding Executive Director Greg Lippman began his career as a teacher at a local public high school in San Jose, where he taught for over 4 years. During that time, he was part of a group of teachers who built a successful school within a school for the highest-need students, but, due to the bureaucratic limitations of the system, was unable to grow that program. This led him to explore the charter school model, and eventually become the founding Principal at Downtown College Prep (DCP), the first charter school in Silicon Valley.
At DCP’s first graduation, Greg was able to celebrate the fact that 100% of the first class of graduates were going to college, but at the same time was forced to reflect on the fact that there were many students who, for a lot of different reasons, didn’t make it to graduation.
ACE was founded to serve the most struggling students.
At that point, Greg committed to building another charter organization focused on the types of students who were failing, even at great schools like DCP. He wanted to build something that was more specifically for those that struggle academically, those that lack the personal momentum or family support to succeed.
When Greg first came to ACE, it was a different organization: the ACE Public School Network, which was started by a group of community organizers and parent leaders from the organization PACT (People Acting in Community Together). PACT had started an organizing movement in East San Jose around quality public schools that eventually led to the opening of several small District schools where principals and families were given the power to design their own schools from the ground up.
However, political considerations threatened the success of those schools, and Greg, along with Susan Hammer (former mayor of San Jose), founded ACE Charter Schools to build on the community movement that the first ACE had started, and to create charter schools specifically designed for the most marginalized students and families in San Jose.
In 2008, the first ACE school opened with 95 5th and 6th graders; in 2017, the first class of ACE high school alumni headed off to college.
ACE Charter Schools has grown by leaps and bounds since opening in 2008, and now numbers four schools (three middle and one high) with over 1,200 students and over 100 alumni in college.
