OBHS Teachers Awarded National Board Certification


National board certified teachers National Board Certified Teachers Dr. Meagan Dissinger and Ms. Andrea Breun.

Oyster Bay High School mathematics teacher Ms. Andrea Breun and choral director Dr. Meagan Dissinger were named National Board Certified Teachers, the highest certification one can achieve in K-12 education.


Only three percent of teachers nationwide have earned the advanced credential, which acknowledges their proven ability to meet the profession’s highest standards. To achieve certification, candidates must successfully complete a performance-based, peer-reviewed process consisting of three portfolios and one examination demonstrating their proven effectiveness on student learning and achievement. About 40 percent of teachers who pursue the rigorous process earn certification.


Ms. Breun and Dr. Dissinger are the first teachers in the Oyster Bay-East Norwich Central School District to be awarded National Board Certification, leading the path for more teachers to pursue the credential. They are among 2,115 National Board Certified teachers in New York State and 125,000 nationwide.


Ms. Breun is in her 17th year of teaching mathematics at Oyster Bay High School. She teaches Advanced Placement (AP) Statistics, Pre-calculus and Geometry, but has taught AP Calculus AB and Seventh Grade Math in the past. Outside the classroom, she is the District Comptroller, working with club advisors and treasurers to oversee activities with Extra Classroom Activities funds. She served as a class advisor in the past. In 2019, she was selected as a Claes Nobel Educator of Distinction by The National Society of High School Scholars (NSHSS) after being nominated by students for her dedication and excellence in the profession. In 2009 she was named Honorary Member of the National Honor Society by its student members. She has also mentored new teachers. In 2007, she worked as an activity coordinator at an English immersion summer camp in the south of Spain. Ms. Breun earned both her Bachelor of Arts in Mathematics Education and Master of Science in Applied Mathematics at LIU Post.


Dr. Dissinger is in her eleventh year of teaching music in public schools, and in her seventh year in the District where she has taught grades K-2 and 9-12. She directs the Oyster Bay High School Chamber Singers, Concert Choir, and general music class for special needs students. In addition to classroom duties, she has served as Vocal Director of the high school musical, and currently serves as adviser for "Breaking Borders,” a club designed to encourage dialogue among Long Island students about various race-related concerns and disparities.


Dr. Dissinger is an adjunct faculty member at Teachers College, Columbia University where she teaches applied piano to music majors and non-majors. She earned a Bachelor's Degree in Music Education with minors in Dance and Special Education from The Pennsylvania State University, a Master's Degree in Piano Performance from CUNY Hunter College, a Master's Degree in Music Education from Teachers College, Columbia University, and a Doctorate in Music Education from Columbia University. 


“Achieving advanced certification elevates the quality of teaching for our students, which in turn leads to greater student success,” said Ms. Sharon Lasher, Principal of Oyster Bay High School. “We applaud the hard work and dedication that Ms. Breun and Dr. Dissinger have put into the National Board Certification process and know that they will continue to make a significant and lasting impact on our students throughout their careers.”
