David Stelmazewski:  Committed to Excellence

David Stelmazewski is a devoted educator with 40 years of experience teaching and leading in public schools. Mr. Stelmazewski became superintendent of Boerne ISD in December 2011. In his tenure as superintendent, Mr. Stelmazewski has focused on three areas of emphasis that interlace to assure a meaningful educational experience for each student in the district.

  • Innovative instruction. Mr. Stelmazewski believes that accountability is important but that teaching and learning extend well beyond results on standardized tests. He has encouraged principals and teachers to utilize innovative teaching methods, engage students in project-based learning, and help all students prepare themselves for the world in which they will live.
  • Solid Financial Position. Mr. Stelmazewski had a hands-on role in developing and promoting bond packages in 2016 and 2013 that received broad community support. These initiatives positioned the district to serve current and future students, addressing steady enrollment growth, upgrading aging facilities and classroom technology, and improving campus security district-wide.

"I'm so proud of the students of Boerne schools and their determination to excel academically and across the spectrum of extracurricular activities." 

                    -- David Stelmazewski

  • Community Partnerships. Mr. Stelmazewski has made the development of community partnerships a priority for Boerne ISD. This support takes many forms, including Boerne Education Foundation activities, businesses offering internships for Career and Technical Education students, PTO fundraising, and much more.

Mr. Stelmazewski arrived in Boerne in 2008, serving as the first principal of the newly opened Boerne-Samuel V. Champion High School. Under his leadership, Boerne-Champion quickly rose among the state’s leading academic campuses; the school attained Exemplary status in 2009, 2010 and 2011. 

Prior to his service in Boerne, Mr. Stelmazewski served as principal of McCollum High School in San Antonio’s Harlandale ISD for seven years. He also served a three-year term as principal of Kingsborough Middle School in Harlandale.

Serving in San Antonio’s Northside ISD, Mr. Stelmazewski was assistant principal at Tom C. Clark High School and teacher and varsity basketball coach at John Jay High School. Mr. Stelmazewski’s career in public education began in 1974 at Woodlawn High School in Woodlawn, Illinois, where he served as teacher, coach and athletic director.
