Our Teachers

Mariama O’Brien

Director and Teacher

​I was drawn to WPCS because I love the co-op philosophy of the school that includes parents and teachers working together. Most of my time teaching over the last twenty years was in co-op schools like this. I bring whatever knowledge and experience I may have to help nurture this community now and in the future.

I am a Liberian immigrant. I lived in West Philadelphia during my childhood, but now I reside in Mount Airy. I have one daughter who is turning ten. I love animals. We have one dog and two cats. I also love music and dancing. Over my career, I have played percussion professionally and currently I play music for children in a band called “Music with Gina.” My favorite food is rice. My favorite color is earthy red.

Alex Brown

School Administrator and Teacher

​I was born and raised in Philadelphia and have lived and worked all over the city. Trained as a clinical social worker, I have worked as a trauma therapist for over a decade helping children and families heal from trauma, tragedy, and hardship. It was through this work that I discovered my passion for working alongside children and families. While being in the classroom is a newer role for me, teaching, learning alongside, and advocating for children and families is not. My experience has been centered around families with youth ages 2-18 and in working with such a diverse age range, I have learned that each child’s experience of the world varies vastly. One of the most rewarding parts of being a teacher is seeing the world through the eyes of a child. Sidewalks quickly turn into raceways, trees are for climbing, and nothing seems yummier than an old fashioned mud pie. I live for these moments with children and I am so excited to be a part of a teaching team that values the same things I do.

I currently reside in West Philadelphia with my dog Hilda and several cats. I love daydreaming, being in the sun and making ice cream from scratch. ​
