BCBrianna Cingari

Math Teacher 

Ms. Cingari was born and raised in Sheepshead Bay, Brooklyn... also born and raised a DOE public school kid. Ms. Cingari always went to the school of her choice, Midwood HS to John Jay College and now Touro College where she is working on a master's degree. Science was always something that piqued her interest but never something that resonated enough with her. As a result, she spent 4 years in a lab as an undergrad and earned a degree in forensic science and a 1st place CSTEP conference award for organic chemistry research. As good as that was, it wasn't her passion. Ms. Cingari's passion was to teach, which stemmed from practicing Taekwondo for 18 years. She started when she was 5 and hasn't stopped yet! Her instructor groomed her to be a leader... an instructor... and educator. So the final step was using her gift for numbers and all things math. Since she was a little girl, her dad told her that numbers were her thing. As a math teacher, Ms. Cingari is combining her gift with her passion.
