Our Staff

Each room is staffed by a Lead teacher with early childhood education.  Our lead teachers have Montessori certification, Montessori professional development training or the opportunity to acquire the certification through AMS. All professional staff meet yearly requirements for continuing education with additional trainings.

All staff participate in Professional Development opportunities throughout each school year and are given the opportunity to attend Montessori-based workshops and conferences.

Teacher-student ratios are 1:5 (Young Toddler), 1:8 (Toddler House) and 1:12 (Children’s House and Kindergarten). Lead teachers have assistants who have completed various levels of certified Montessori training.

Teachers and assistants are assessed each year by the Head of School and the parents so that the staff is continually improving their skills and capabilities.

Teacher Training

  • All Day Montessori teachers are Montessori certified or are in the process of completing their certification.
  • All lead teachers have bachelors degrees in education or comparable student teaching experience.
  • Assistants are strongly encouraged to complete their undergraduate degrees.
  • All Day Montessori requires all lead teachers to complete their Montessori certification and provides financial assistance for this purpose.

Shannon O’Keefe-Anderson
Co-Lead Teacher
Hello my name is Ms. Shannon. I have recently joined All Day Montessori in January 2021, but it already has my heart. I started off as a substitute teacher, working with all ages at the school. I co-taught in CH1 with three to six year olds.  I have known for years that I wanted to make a career out of working with children because they really light up my life. I started my career working at daycares. I pursued my Bachelor’s degree in Social Work, which led me to working in DCFS as a caseworker. After leaving DCFS, I returned to my previous daycare and received my Teaching Certificate. I happily worked as the teacher for the infant room for two years. Prior to coming to ADM, I had nearly seven years working professionally with children along with fifteen years of informal experience. When I am not at work, I enjoy spending time with my husband and our animals. My goal as a teacher is to provide a complete education to all children with love and fun.

(Shannon is currently in the Infant/Toddler Montessori Endorsement Program through Seton Montessori.)
