BCBrianna Cingari

Math Teacher 

Ms. Cingari was born and raised in Sheepshead Bay, Brooklyn... also born and raised a DOE public school kid. I always went to the school of my choice, Midwood HS to John Jay College, now doing my Master's in Touro College. Science was always something that piqued my interest but never something that resonated with me, so I spent 4 years in a lab during my undergrad landing me a degree in Forensic Science and a 1st place CSTEP conference award for my organic chemistry research. As good as it was, it wasn't my passion. My passion was to teach; this stems from my 18 years of Taekwondo. I started when I was 5 and haven't stopped yet, my instructor groomed me into a leader... an instructor... and educator but again I knew that Taekwondo wasn't where I was meant to be. So the final step was my gift for numbers and all things math. Since I was a little girl my dad told me that numbers were my thing and it always resonated with me. Here I am, as a first-year teacher, combining my gift with my passion and co-teaching Algebra 1 & 2.
