Testimonials

"Yael was a fantastic asset in her role as a Board Member at Udon Thani International School (UDIS). Yael was able to consistently leverage and communicate her vast experience in the international school context to inform and advise the Board's decision making, strategy and overall direction."

Dr. Lindsay Stuart Head of School, Udon Thani International School, Thailand
"Dr. Yael Cass was a game-changer during my time as an international school principal. Navigating a predominantly male environment as a female leader was challenging, but with Dr. Cass's mentorship, I found my stride. She honed my leadership skills through personalized development plans, engaging discussions, and a curated selection of professional articles and books.

Dr. Cass is a powerhouse of knowledge and an out-of-the-box thinker who brings energy and innovation to every interaction. She taught me how to work smarter by refining my approach and deepening my understanding of school operations. Our relationship was built on trust and openness, making it easy for me to seek her guidance whenever challenges emerged. Dr. Cass’s mentorship was transformative, and I wholeheartedly recommend her services to any woman leader or operational leader looking to elevate their impact and effectiveness."

"Successful schools thrive on critical friendship. Dr Yael Cass provided exactly that for Mt. Zaagkam School and our sister School Yayasan Pendidikan Jayawijaya in Papua, Indonesia.  Dr. Cass was providing consultancy on innovative campus designs in a cross-cultural context. Yael navigated the nuances of cross-cultural communication with effortless skill and professionalism. She transferred knowledge and skills, built conceptual understanding and generated creative thought and inspiration. Dr. Cass’s vast knowledge of organizational culture abounded. As a team of educators, the importance of school culture and empowerment was central to our conversations as the schools build an innovative future. A friendship that will endure and resonate for years to come."
