Celina Midelfart
Board Trustee
Oslo International School (OIS)
“Faced with significant structural and operational challenges, the Board entrusted Jon to provide clear, evidence-based insight and a decisive roadmap for change. During a subsequent leadership transition, he stepped in as de facto COO/CFO - stabilising operations, implementing critical reforms, and modernising admissions, financial, and operational practice. His ability to work with credibility and partnership across the Board, Head of School, and organisation was instrumental in moving OIS toward a more resilient and sustainable footing…”
Dr. Mike Johnston
CEO
St. Joseph's Institution International (SJII - Singapore)
“We engaged Jon Hansen / GSO following strong recommendations from respected heads of school. What began as an ICT review quickly expanded into a whole-institution operational scan, giving us rapid, high-ROI clarity across systems, practices, and the organisation - leading to Jon’s re-engagement to secure our admissions and continue as a long-term strategic and operational partner…”
Rachel Caldwell
Head of School
American International School of Bucharest (AISB)
“From a schoolwide operational policy review, we've quickly evolved into a long-term strategic partnership with Jon - aligning our Board, strengthening leadership and workforce practice, and leading directly into Phase 2 execution to build a future-ready operational foundation. We are now evolving our full People and Culture program. Jon is now a deeply trusted advisor to me, my leadership team, and our Board as we continue to evolve the school with clarity, care, and confidence…”
Wayne Rutherford
School Director
The American School of Milan (ASM)
“ASM's initial comprehensive Admissions and Enrollment Management audit has now evolved into a multi-year operational partnership spanning finance, facilities, and schoolwide policy architecture. Jon’s work at ASM has provided deep, objective insight across systems, practices, and organisational structure - strengthening our admissions performance, clarifying our financial health, informing the foundations of our future Master Facilities Plan, and now rebuilding our full operational policy framework. Across each phase, Jon has been a steady, highly credible thought partner to me and our leadership team, bringing clarity to complex decisions and helping ensure that our strategic intent is supported by a strong, disciplined operational foundation…”
Brett Penny
School Director
American International School of Budapest (AISB)
"We engaged Jon at a pivotal strategic moment, and his operational review gave us clarity, prioritisation, and a practical roadmap - strengthening systems, maturing practices, and enabling our leadership team to move confidently into the school’s next phase of evolution. I only wish I had had this level of operational clarity earlier in my tenure…"
Dr. Bernadette Carmody
School Director
The International School of Amsterdam (ISA)
“Across two international schools, Jon rebuilt foundational governance and operational policies and stepped in under extreme time pressure to lead admissions - delivering record enrolment and 100% on-time payment at one school, and earning long-term trust as a retained strategic partner. He continues to serve as a transformational leadership advisor to my Board, leadership team, and myself at my current school, helping evolve the workforce for future-ready resilience…”
Dr. D.J. Condon
School Director
International School of Luxembourg (ISL)
“Jon’s review of our Board policies and administrative regulations brought much-needed clarity and balance between strategy and operations, earning the confidence of our Governance Committee and leading to his re-engagement for follow-up Board policy work - much of it involving substantive rewrite and rationalisation…”
Catarina Song Chen
REO for Strategic Initiatives
Office of Overseas Schools,
U.S. Department of State
“As part of a carefully planned leadership transition following fifteen years of stewardship, Jon led a ground-up rebuild of our operational and Board governance policies - creating the structural clarity, continuity, and maturity needed to preserve the school’s identity while enabling sustainable, future-ready evolution. His work strengthened Board governance, aligned policy with bylaws and practice, and provided the incoming leadership with a clear, trusted foundation to lead with confidence. Jon remains a deeply trusted advisor to me and to the school as its governance, operations, and workforce continue to mature through ongoing change…”
Ken Kunin
Head of School
International School Nido de Aguilas (Santiago, Chile)
“Jon’s ability to listen deeply and understand our organisation led to meaningful administrative reorganisation and an enrollment review and system redesign that is already delivering results; exceeding targets, earning Board confidence, and leading to his continued retention as a long-term strategic advisor to myself and my leadership team…”
Ben Weinberg
Head of School
American School of Madrid (ASM)
“During a period of significant staff tension and organisational change, Jon was entrusted to lead a delicate and sensitive cultural and supervision review that helped stabilise the school, restore trust, and guide our next steps. From this transformational work, he was re-engaged to lead Admissions, Communications, and Advancement initiatives to strengthen connection, secure revenue, and embed best practice. I look to Jon as a trusted partner and advisor…”
Dr. Nada Collins
Superintendent

It’s a pleasure to continue calling on Jon as a trusted advisor when clarity, care, and sustainability matter…”
Paul Sanders
Head of School
San Domenico School / Oslo International School (OIS)
“After Jon delivered a comprehensive review of our operations, I asked him to step in as interim COO/CFO during a very difficult period for the school. He became my right hand - bringing calm, high-EQ leadership and deep operational expertise across finance, admissions, communications, facilities, and hiring - while helping our staff move forward without defensiveness or division. I genuinely don’t know what I would have done without him…”
Bill Kralovec
School Director
Tashkent International School (TIS)
“Jon’s work at Tashkent International School began with a foundational scan of our operational policies and evolved into a complete rebuilding of our operational and governance architecture - strengthening clarity, accountability, and long-term institutional health across the school. Through this work, he authored a new Board governance framework, modernised our operational documentation, and designed a fully digital Admissions and Enrolment system that now gives leadership and the Board real-time insight into our strategic and financial position. Jon remains a trusted long-term advisor to me and our Board, supporting leadership development, workforce structure, and preparation for my own future transition…”
Courtney Lowe
School Director
American School of The Hague (ASH)
“Jon led the full digitisation of our Admissions Office - delivering a new platform on time and within budget, strengthening practice across the entire admissions journey, and positioning the school exceptionally well ahead of the unanticipated COVID pandemic. This also proved to be extremely resilient and future-ready when ASH transitioned to a normal operating state…”
Dr. Douglas Ota
Founder/CEO
Safe Passages Across Networks (SPAN)
“Jon’s empathetic, non-threatening presence gave our organisation the safety and encouragement we needed to face a pivotal moment of change - leading us toward clear strategic and operational next steps and genuine organisational development. He helped refocus us on strategy, reground decision-making with the right people, and steer our Board away from operations, so the organisation could move forward with renewed clarity. Jon has a rare ability to listen through complexity, hear an organisation’s true story, and make the few precise adjustments that allow the whole system to move forward again…”
