Elizabeth Petruccelli

Lead Teacher, Director

11 Years

  • B.A., Education, Penn State

  • M.S., Dual Degree in Curriculum and Instruction

  •  Primary Montessori Education (3-6), Infant-3 Montessori Education, American Montessori Institute 

Elizabeth is the Lead Teacher for the Extended Day Program. She is also the owner and Director of our school. Elizabeth is a leader in the Pittsburgh Montessori and preschool teaching community. Her professional experience includes Educational Director and consultant at The Glen Montessori School in Sewickley, Pennsylvania. She has also taught at Mount Lebanon Montessori and was a consultant for Children’s Hospital of Pittsburgh’s Montessori school program.


In 2007, following a brief hiatus to stay home with her 3 children, Elizabeth resumed teaching at here at The Montessori Children’s Schoolhouse. Elizabeth is the Lead Teacher for our Extended Day Program.  As our school leader, Elizbeth continuously cultivates an environment of joy, discovery and peace. She is committed to ensuring that our environment (the first school experience for most of our students) is child-centered, warm, collaborative, self-directed, and dynamic.  Her goal is for children to complete their preschool years as embodiments of Maria Montessori’s description of great scholars: “To produce great scholars will be useless unless they are also integrated, committed, respecting, loving and caring human beings.”


Elizabeth herself embodies the notion of global citizen. As a college student, she traveled the world with The Semester at Sea program and she is also a alumna of Outward Bound. As an adult, travel and learning about other cultures and community service has continued to form her notion of what it means to be an educational administrator and teacher. 


Elizabeth grew up in Mt. Lebanon and after living in Denver and Cleveland, she returned to raise her family. She has three children; Michael 18, C.J. 16, and Sommer, 14. Elizabeth is on the board of various non-profits including The Samburu Project (clean water initiative for the women of Kenya).  She is an avid practitioner of Pilates and yoga and she also enjoys gardening, skiing, and Pittsburgh’s cultural art scene.

Bonnie Noone

Lead Teacher 3-6

23 Years

  • B.A., English Education, The College of New Jersey

  • Certification, Early Childhood Education (N-K), California University of Pennsylvania

  • Primary Montessori Education (3-6), Center for Guided Montessori Studies


Bonnie is a Lead Teacher for our 3-6 Program. She is in her 23rd year of teaching at our school and her 30th year as a teacher. Bonnie began her career as a high school English teacher. After starting her family, she became an assistant in a 3-6 Montessori school. She was delightfully amazed by what Montessorians refer to as normalization among so many young children. Bonnie began to read everything she could find about Montessori philosophy and education and observed many Montessori classroom environments. Bonnie’s enthusiasm, delight and endless curiosity in Montessori philosophies and child development continue to inspire us.


As a Lead Teacher and Montessorian, Bonnie has set a unique tone and standard for our teachers. Bonnie is a keen observer and reflector of children.  Through her example, she has taught us to step back and observe, then refine our works and lessons to each child accordingly. She encourages independence and exemplifies the subtle difference between helping and guiding.

Bonnie and her husband, Brian raised their family in Peters Township, where they continue to reside. They have two daughters, one son and two grandchildren. She enjoys exercising, reading and traveling with her husband.

Personal Statement: I believe children learn by our examples. When we are joyful to begin our day, they will also see the joy. When we greet them with a welcoming smile, they will know they belong. When we express our excitement at their efforts, they will become confident to explore. Most children are with us for 3 or 4 years. During this period, we have the unique privilege of observing them grow as they independently select work from the shelves, explore with confidence and concentration, and show pride in their effort for success. By the time they move on they have become eager leaders, inquisitive learners, kind friends and children who realize that they are world citizens and important members of their communities.

Danielle Cain

Lead Teacher 

  • B.A.,  Xavier University

  • AMS Montessori Certification 

  • Certification, Early Childhood Education 

Danielle is starting her first year as a Lead Teacher in our 3-6 classroom. She attended our school under the direction of Martha Feldmeier from 1998-2000. From here she moved to Mt. Lebanon Montessori where she fell deeper in love with the Montessori philosophy. When it was time to start applying to colleges she took a risk and applied to only one, Xavier University, where she received her AMS Montessori credential as well as an Early Childhood teachers certificate.

Danielle grew up in the South Hills of Pittsburgh. One of her favorite things to do is coach gymnastics. She began coaching and competing for Gymsport at the age of 12. Her favorite thing to do outside of school and work is to craft. She loves DIY projects and recently taught herself to crochet. Part of my soul belongs on a boat as I love to cruise, with Antigua being my favorite port-of-call. Danielle's favorite Montessori material is a tie between the movable alphabet and the golden bead materials.
She feels honored and blessed to have been asked to come back and teach as an Alumni. She is excited to see where this journey takes us as a community.
