Gregg Fleischer

Gregg Fleisher


As President, Gregg serves as NMSI's key liaison with senior school district leaders, state and national STEM education partners, and public and private funders while continuing to provide strategic direction and oversight of NMSI’s core programs to ensure program fidelity and sustainability.Read

Gregg started his career as an auditor and actuary, but found his true passion as a math teacher. In 1995, while continuing to teach AP Calculus, Gregg started the AP Incentive Program (now known as NMSI’s College Readiness Program) in Dallas ISD. During his five years with the program, as much as 3.3 percent of the country’s minorities who earned qualifying scores on AP math exams were from Gregg’s ten Dallas ISD schools.

In 2000, Gregg was asked by Dallas philanthropist Peter O’Donnell to lead the nonprofit Advanced Placement Strategies (APS), which managed the College Readiness Program for districts in the state of Texas. In seven years, the fledgling company grew from four to 60 employees, had an annual budget of $15M raised from private and public funds, and had programs in hundreds of schools in the state. The average program saw qualifying scores in math, science, and English triple within five years. The success of APS gave ExxonMobil cause, in part, to commit to NMSI their largest grant ever to replicate the program in other states.

In 2007, Gregg joined NMSI to oversee the $79M in grants given to nonprofits in six states that were initially slated to replicate the College Readiness Program. The program has since been implemented in nearly 800 schools across 30 states. Today, Gregg continues to oversee the College Readiness Program as well as NMSI’s Laying the Foundation Teacher Training Program for grades 3-12 and the UTeach Expansion Program, which is helping to prepare the next generation of math and science teachers.
