Ornsirin Education Invests 1,000 Million Baht to Make History with the Launch of Mill Hill International School Thailand – The First Authentic British-Branded International School in Chiang Mai
Ornsirin Education Co., Ltd., a subsidiary of Ornsirin Holding Public Company Limited, a leading property developer in Northern Thailand, is stepping into a new chapter. With an investment of over 1,000 million baht, the company proudly announces the launch of Mill Hill International School Thailand—the first premium British international school in Chiang Mai. This historic milestone marks the first expansion of Mill Hill Education Group outside the United Kingdom, signaling a new era for international education in Northern Thailand.
With over 200 years of academic history, Mill Hill School combines British educational excellence with the global vision of “Connecting the World,” aiming to develop future leaders who excel in all aspects of life under the philosophy of “Instilling Values, Inspiring Minds”. The school is set to open on 1 September 2025.
Mr. Akkadet Udomsirithamrong, Deputy CEO of Ornsirin Holding PCL and CEO of Ornsirin Education Co., Ltd., shared his vision:
“We have observed a strong growth in the international school sector in Thailand, particularly in Chiang Mai—an expanding economic hub and a famous tourist destination that continues to attract expatriate families and Thai households. Although there are already over 25 international schools in Chiang Mai, we still see a tremendous opportunity to elevate the education toward global standards. With our experience in real estate development and a strong presence in Chiang Mai, Ornsirin is proud to support the establishment of Mill Hill International School Thailand, as part of our vision to create a complete Lifestyle Ecosystem for the students and their parents”
He continued, “Currently, there are very few institutions in Thailand officially recognized as British Branded Schools, which truly reflect one of the highest standards in global education. To address this, we’ve signed an MOU with the prestigious Mill Hill Education Group from the UK—an academic institution with over 200 years of history. This partnership brings not only the curriculum, but also the staffs and management directly from the UK, making this a major development in the region’s educational landscape.”
One of the keys to success lies in strong leadership, and to this end, Kate Simon, Head of Grimsdell and Founding Head of Mill Hill International School Thailand, has flown in directly from the UK to serve as the first Head of School in Thailand. She leads a team of educators committed to deliver an education that meets the British standards. Furthermore, Dr. Yuthachai Damrongmanee, a highly experienced figure in international education, joins as School Director, reinforcing the mission to provide quality education that meet the needs of both students and their parents.
With its authentic British curriculum and world-class facilities, Mill Hill International School Thailand offers extraordinary value—providing the same level of education as its UK counterpart but at a far more accessible tuition fee, making it an exceptional investment for the children’s future.
Kate Simon, Founding Head of School of Mill Hill International School Thailand, spoke about this strategic partnership: “Mill Hill School was founded in London in 1807 and has developed a unique educational philosophy that has stood the test of time. As part of the Mill Hill Education Group, we’ve built a global network of school partnership, and our alumni have gone on to achieve international acclaim in various fields—including business, education, arts, sports, literature, and film. Notable names include Sir Denis Thatcher, husband of former UK Prime Minister, Margaret Thatcher; actor Harry Melling from Harry Potter; legendary royal fashion designer Sir Norman Hartnell; and world-renowned historian Prof. Sir Richard Evans, among many others.
