Anita attended the University of Illinois and Northeastern Illinois University, and received a B. S. degree in Biology with secondary certification to teach Biology and general science. She holds a Master’s Degree in Educational Administration from Temple University in Philadelphia, and holds National Board Certification in Early Adolescent Science.

She then moved on to the Philadelphia School District, where she spent the rest of her career. Anita was a middle school science teacher, and the science curriculum specialist for middle years for the School District of Philadelphia, Pennsylvania. As Anita herself explains, “When I retired I felt that I wasn’t done with science education, that there was just too much more to be said about the importance of a ‘science literate citizenry.’ So I have continued to work as an educational consultant, and now as a member of the GreenTreks team.”
