Our Team

The Prepared Montessorian team consists of a diverse, growing group of educators, school leaders, and professionals with decades of combined experience in the field of education and education management, at dozens of varied Montessori schools, across multiple countries.

Joel Mendes

Executive Director of Prepared Montessorian, Orange County, Calif.

Joel Mendes has studied in or worked in schools since his own preschool experience as a child. From California State University Long Beach, he earned a Bachelor of Arts in English Education and Literature and a California Teaching Credential. He began his career teaching English, writing, and literature to varied groups of students - including sixth graders in an inner-city charter school, high schoolers in a public high school, and to adults at an international college - all the while realizing that innovation in education takes both new ideas and efficiency in school operations and management.

Joel then became Head of a Montessori school for children ages 18 months to eighth grade, and the experience changed him. Not only did he have the chance to work with remarkable Montessori children, but he witnessed first-hand the benefits of Montessori as a father to three children in the school. He dove in completely, earning his AMI Primary Diploma and continuing to advocate for Montessori education.  

In 2016, he became the founding Executive Director of Guidepost Montessori and began mentoring Montessori school leaders. Today, he brings his expertise to Prepared Montessorian as a leader in creating and delivering high-fidelity trainings and resources to practicing Montessorians. He enjoys watching the Dodgers, cooking for his family and friends, and holding himself to a standard of living he’d be proud to see emulated in his three children.

Monique Shen

Nido and Toddler Jr. Trainer and Coach, New York, N.Y.

After earning her Bachelor of Arts in Psychology from Stony Brook University, Monique continued to pursue her interests in developmental psychology and found that her true passion was in early childhood education. She first began her career in education assisting Board Certified Behavior Analysts that utilized applied behavior analysis (ABA) to serve children 5 to 18 on the autism spectrum, but eventually found that the Montessori approach more closely mirrored her natural style and aligned with her personal philosophy, where each child is supported with love and respect in their journey of self-creation. She then graduated with her AMI Montessori Diploma for the Birth to 3 age group from The Montessori Training Centre of British Columbia in Vancouver, Canada, and is currently pursuing a dual master's in Early Childhood and Special Education.
