This remarkable portfolio of student-centered programs was envisioned and developed under the leadership of Dr. Mathew Mandery ’61, the only Brooklyn Tech alumnus to have served as the school’s principal. A member of the Brooklyn Tech Alumni Hall of Fame and one of the Foundation’s three co-founders, Dr. Mandery has been the driving force behind its educational mission for over two decades. As Chief Educational Officer, he created and directed all of the Foundation’s major student initiatives—including the Weston Research Scholars Program, the Algebra Initiative, and numerous academic, research, and enrichment partnerships that now define the Tech experience. Honored at the school’s Centennial Gala in 2022 alongside fellow founders Michael A. Weiss ’57 and Achilles Perry ’58, Dr. Mandery’s legacy is deeply embedded in Brooklyn Tech’s evolution as a national model for alumni-supported public education. Seinfeld joins the Foundation as Dr. Mandery begins a transition to the role of Chief Educational Officer Emeritus.

"Passing the baton to someone of David’s caliber gives me great confidence,” said Mandery. “His understanding of instruction, leadership, and systemic change makes him incredibly qualified to carry the Foundation’s mission forward. I am excited to work with him this year and beyond.”

Seinfeld’s professional journey includes leadership roles at Martin Van Buren High School and Robert F. Kennedy High School in Queens, and Calhoun High School in Merrick, where he served as principal for over a decade. Later, as Assistant Superintendent for Curriculum, Instruction, and Assessment in the Bellmore-Merrick Central High School District, he championed district-wide innovations in teaching, learning, and technology integration.

Outside the classroom, Seinfeld has served on the boards of Community Mainstreaming Associates, FIRST Robotics LI, and Virtual Enterprise International, and is a longtime trustee of the Roslyn School Board of Education. He has also been honored as District Administrator of the Year by the Long Island Foreign Language Supervisors and is a Calhoun High School Hall of Fame inductee.

“David’s leadership reflects a rare blend of instructional depth and strategic vision,” said Courtney J. Ulrich ’90, Executive Director of the Brooklyn Tech Alumni Foundation. “He understands how to translate educational innovation into real opportunities for students. We’re excited for the ways he’ll strengthen our programs and expand their reach across Tech’s vibrant community.”

David and his wife, Dr. Laura Seinfeld, are lifelong educators and parents to two sons and daughters-in-law—all of whom are educators themselves. David and his wife are now grandparents to Hayden and Willow, who “seem destined to continue the family tradition.”

“Joining the Brooklyn Tech Alumni Foundation feels like coming full circle,” Seinfeld said. “It’s a chance to use everything I’ve learned to support one of the most dynamic student bodies in the country.”

As Program Director, Seinfeld will work closely with administrators, educators, students, alumni and external partners to ensure that Brooklyn Tech remains a national leader in public STEM education—one opportunity at a time.
