Message from the Head of School

Dear MCS Community -


It is with profound gratitude for the opportunity to be Montessori Community School’s Head of School for the past seven years that I announce my retirement at the end of this school year, on June 30, 2024. 


It has been an honor to serve the MCS community of students, families, and staff. I am proud of our shared achievements including reaccreditation with both the American Montessori Society (AMS) and the Hawaii Association of Independent Schools (HAIS), the development of meaningful goals for improving our school, as well as keeping our ship on an even keel throughout the Covid-19 pandemic crisis. It has been a wonderful experience that has afforded me many opportunities to learn and grow, and I feel privileged to have been part of this organization. Be assured that I will support our school community to advance our mission to provide an excellent Montessori program to our students in the days to come. 

In preparation for the transition, the MCS Board of Trustees assembled a Head of School Search Committee and hired a search consultant, RG175, to find the next perfect fit for our school. After a thorough search process, we couldn’t be more thrilled to welcome Jyo Keakealani Bridgewater as our new Head of School for the 2024-2025 school year.

Jyo Keakealani Bridgewater grew up on Maui and graduated from Baldwin High School, Yale University (BA, cum laude), and New York University School of Law (JD).


Jyo is an experienced independent school administrator, retains Montessori 6-9 certification, and served as adjunct faculty in the Montessori-intensive Master's program at Chaminade University. Jyo taught in the MCS 6-9 Program, serving as a teacher in Room 1 for several years, after being a substitute teacher in the 9-12 Program. She was the Principal of Assets School's Lower School, and most recently has been the Principal and 6th grade teacher at Holy Nativity School.


Jyo’s service in education includes not only independent schools, but also special education, differentiated instruction, and Hawai‘i’s DOE charter schools. She has mentored teachers, presented at international gifted conferences, and has led numerous parent education events and forums. Currently, Jyo serves on the Executive Board of the Hawaii Association of Independent Schools, and chairs the private school licensing council.


“What an honor it is for me to be a part of Montessori Community School again, and to be a part of the profound and essential work you do here. Stepping onto the campus a few months ago, I felt an overwhelming sense of the joy and commitment that has always been MCS’ hallmark.  I look forward to coming home to Montessori and to being with all of you.” ~ Jyo Bridgewater 


I look forward to enjoying my work at MCS, great colleagues and friends, and my island home for the remainder of the school year.  


Mahalo nui loa ~ Marjie
