Dr. Bernadette Carmody, Head of School
The International School of Amsterdam (ISA)

Due to his vast leadership experience in systems and operations, we relied on GSO and Jon's insights in all sorts of areas in the strengthening of our business operations. Most importantly, with very short notice, he stepped into the role of Director of Admissions. 


Jon brought to the role a perfect blend of people skills and task management skills, capturing our highest-ever enrollment, and he secured a very rare 100% of full tuition payment before the commencement of the following school year with a new Director.

VPS engaged GSO and Jon to lead the update of our core policies and procedures for our international school clients. He exhibited exceptional diligence and an eye for detail and brought a deep understanding of international school operations and policy.


It is very evident that GSO looks holistically at clients and schools and delivers superb results in a highly efficient and easily systemized manner. His extensive domain knowledge and real-world experience helped deliver on our requirements and beyond.

GSO and Jon led the digitization of ASH's Admissions Office. During this critical project, which he completed on time and within budget, he customized and implemented an entirely new technology platform and effectively trained all key users across ASH.


He also provided valuable strategic and tactical insight to the ASH Leadership Team and key stakeholders on a variety of other topics and practices. A savvy and creative design thinker, Jon is positive, flexible, adaptable and a great team player who quickly builds rapport.

GSO and Jon were key to ensuring that I had a seamless transition to this position. He gave me mature and transparent communication tools that he'd created and already made AISG's new Director and Board fluent with in addition to fully improved operations.


Jon also secured the school's highest-ever enrollment and 100% full payment before I arrived. This while implementing a new Veracross portal and screening/hiring one of my top analysts. It was a great situation to inherit and I highly recommend working with GSO/Jon!

Jon has excellent knowledge of international school admissions, IT skills, and project mgmt, so was the ideal person to work with. The project was large and his leadership and positive attitude played a huge part in helping it to be a successful and enjoyable experience.

I am happy to be supporting him again in his role as Acting Chief Financial and Operations Officer at Oslo International School and hope that I may continue to have the opportunity to work with Jon and GSO on future IT projects!
