Why Sea Change

Because schools are built on relationships.

When teachers and students feel seen, supported, and connected, the entire school flourishes.

Sea Change helps international schools weave SEL and wellbeing into daily life—through practical tools, responsive frameworks, and collaboration that respects your unique culture and context.

What we do

  • SEL & Advisory

    Reimagine advisory as a space for real connection.

    We help schools design authentic, developmentally aligned SEL and advisory programs that reflect students’ lived experiences—not a script.

  • Wellbeing & Climate

    Create systems that care for both students and adults.

    We guide schools in embedding wellbeing into policies, routines, and culture, so care becomes part of the structure, not another item on the list.

  • Leadership & Mentoring

    Support for the people who shape your school’s culture.

    We mentor leaders through change, crisis, and growth—building trust, alignment, and coherence across the community.

  • Crisis Response

    Guidance when your community needs stability most.

    From war to natural disasters, we help schools navigate trauma with calm, culturally attuned strategies that hold both care and direction.

What our partners say

What our partners say

  • “Working with Sea Change Mentoring has deepened our faculty’s understanding of social-emotional learning and the importance of a responsive, contextualized approach that reflects our community’s culture.”

    The SEL Learning Roadmap has given our teams a clear framework to work from. Over the past couple of years, it has helped us successfully generate topics and themes, while encouraging us to experiment with different SEL instructional approaches and routines. As a result, we’ve seen increased student voice and engagement, along with a stronger sense of belonging and connection between students and faculty.

    – Jackie Whitney, Middle School Associate Principal and Head of the Schoolwide SEL Committee, American International School of Riyadh

  • “Working with Sea Change has provided us with a fresh way of looking at our approach to SEL so that it's an integral part of our school's identity, culture and daily practices.”

    Through ISM's collaboration with Ellen, we dovetailed our efforts to strengthen intercultural competency so that we can honor and live our commitment to nurturing individuals and building a community that flourishes and thrives. With each step, we keep growing and learning more!

    – Clarissa Sayson, Assistant Superintendent, International School of Manila

  • “Ellen is a skilled practitioner whose work is infused with a deep, nuanced understanding of the challenges that accompany life for those who work internationally.”

    Drawing on her own experience as an international student, she easily relates to and connects with international teachers and students. At CIS, we’ve collaborated with Ellen on a range of projects, related to well-being amidst the transitions that all international educators and students must navigate as they move from school to school or school to university. Each time, our work with her was successful and fun. When school or university members call us to ask for help in these areas, we recommend Ellen with great confidence, particularly during this challenging time of anxiety and uncertainty due to school closures, remote learning, travel bans and quarantines.

    — Jane Larsson, Executive Director, Council of International Schools

  • “Ellen Mahoney challenges educators to embrace co-learning with students in an era where social media often fragments our attention.”

    In her plenary at the NESA Learning Futures Summit, she invited us to ‘listen more deeply, turn to each other, and share the journey with compassion and intelligent care for social-emotional well-being.’ Her message was a resonant call to action that inspired the NESA community.

    – Madeleine Hewitt, Executive Director, NESA

  • “The AISH summer seminar led by Ellen was truly exceptional.”

    Her passion for the role of relationships in wellbeing and learning guided us to reconnect with our core values and equipped us with strategies to enhance our own self-awareness and resilience, and to protect the well-being of our communities. Ellen created a supportive and nurturing environment through her calm and inclusive approach. It was an outstanding experience that left a lasting impact on me and, I believe, on all of the participants. I am grateful for the opportunity to have been a part of it.

    – Rachel Caldwell, Head of School, American International School of Bucharest

  • “Ellen provided a space for leaders to connect, share and reflect. She led with both passion and compassion, and I appreciated her ability to tailor the sessions to meet the needs of our diverse group.”

    – Carrie Dietz, Head of School, Australian International School, Singapore

  • “The summer seminar was so well orchestrated and supported by Ellen. With each passing day it increasingly became a place of trust and personal and professional inspiration that I will keep resorting to for quite a while.”

    – Marta Medved, Head of School, Western Academy Beijing

  • “I was struck by the thoughtful way the course was designed, the well-chosen articles and videos and the engagement we had with our colleagues in the course.”

    In the middle of a challenging year I wondered how I would fit this in to my time and work load. I was struck by the thoughtful way the course was designed, the well-chosen articles and videos and the engagement we had with our colleagues in the course. The reading was not overwhelming and at the same time it was thought provoking and insightful. The time we spent each week reflecting what we learned with colleagues in our time zone was beneficial to hear what other professionals were facing in our region and gave support to my own work. I finished the course with a renewed drive to do better for our faculty, our school and for myself.

    – David Munro, High School Principal, American School of The Hague
