Mary has served NYC public schools as a teacher, Title I Math Instructor, District 28 Math Staff Developer, JHS 217Q Assistant Principal, then Assistant Principal and Principal of PS 196 Queens. After a very brief retirement (two months) she was recruited by Cambridge Education to introduce the Danielson Rubric to school leaders in the Hillsborough School District in Florida. She has also taught education classes at Yeshiva University and Queens College. She has since served the Executive Leadership Institute as a mentor, consultant, and coordinator, creating and delivering workshops for new school leaders throughout NYC. Most recent among these co-created programs have been workshops on bias, executive function, school environment and mental health. She continues to mentor and deliver up-to-date instructional and administrative strategies and protocols for the challenging times in which we live today.
