Cathy O’Reilly started her career in neuroscience research when she earned her Bachelor of Science in Biochemistry from San Francisco State University. Realizing how much she loved sharing her knowledge and love of science with others, she obtained her Master of Science in Biology teaching. Cathy has been happily honing her craft since 1988 and has been at Mamaroneck High School since 1994. Having taught all levels of Chemistry and Biology, she is currently the Department Chairperson and AP Biology teacher.

Cathy maintains her love of “all things science” by going on Eco-adventures with like-minded educators and zookeepers. Thus far, she has traveled to Mexico, Costa Rica, Belize, Borneo, Venezuela, Africa, and Peru. Each trip is focused on specific Ecosystems and animals. This past summer Cathy explored Birds and Insects in the Amazon rainforest. Each adventure allows her to bring back new knowledge and insight to the classroom to excite a new generation.

Both of Cathy’s sons took Carnegie Prep classes, and she has been teaching the SAT Subject Test in Biology for Carnegie Prep since 1997.
