Having started as a foreign language teacher (French and English), Ms. Aarnaes has worked within the private educational sector, within both national and international schools in Norway, Belgium and the UAE. She came to Dubai in 2017 to set up and be the Founding Head of Dwight School DubaI, an IB World School with a strong American legacy. Prior to that she held the position as Head of School at Oslo International School (OIS) in Norway, also a cutting-edge private K-12 co-ed IB World School.

Including her first seven years as Head of School at Sonans Oslo, she has held a strategic project role as Business Development Manager at the Scandinavian School of Brussels (SSB), where she also served on the Board of Governors. As someone who embraces opportunities that expand her horizon she stepped out of the field of education for a few years and worked at the EFTA Surveillance Authority in Belgium, a judicial inter-governmental institution tasked with monitoring implementation of EU legislation. Her experience furthermore includes stints with private educational start-ups, such as the Sonans Privatgymnas, a Norwegian high school for adults, where she was the Founding Director, and for performing a demerger at SSB that resulted in the founding of the Norwegian School of Brussels (DNSB).
Ms Aarnaes is a futurist and serves as a member of the Dubai Future Council on Education, where she takes part in forging paths for the UAE’s 2071 strategic vision in areas of learning and knowledge economy. She is also the Vice-Chair of ECIS (the Educational Collaborative for International Schools) and an active participant in the IB World Community, a trained CIS team visitor and in process of becoming a NEASC accreditation visitor.

She is passionate about disrupting traditional educational mindsets, contextualizing learning and rendering education purposeful for the individual student. She is thrilled to be joining the rich learning community at UAS.
Deputy Director and Elementary School Principal – Stephanie Chattman
For over 23 years Dr. Stephanie L. Chattman has dedicated her entire professional career serving kids, families, and communities. She has made it her personal mission to be a professional educator and to promote personal empowerment, social development, and perpetual progress through the power of education. She believes that education is a continuous journey, that every experience, endeavor, and obstacle that one encounters is an opportunity to enrich one’s understanding of self and to gain additional knowledge. Education isn’t just her profession, it’s her passion, her mission, and her mechanism to help make the world a better place.
Her career began in her native state of Alabama where she served as a social worker assisting families in ways that improved their lives through training, housing, and financial assistance. The driving force behind every decision that she made was the question, “what is best for the children.” She knew that one of the best things she could do for children was to ensure that they received a quality education. That idea led her to pursue a career as an educator. Although she understood her dedication to transforming lives required her to be more than a teacher but rather she became proficient at the art of education and a professional educator.
After obtaining a teaching position in Georgia, she and her family relocated there. Dr. Chattman began her teaching career as a Special Education teacher that focused on inclusive practices. This is an ideal that she continues throughout her practice now. While she taught in an elementary school in Dekalb County School District, she continued to pursue her own professional growth. She took every opportunity to acquire additional certifications, professional development, and valuable experience all while eventually obtaining her masters, specialist, and doctoral degrees in Educational Leadership. Her drive, her passion, and her personal pursuit of excellence was quickly recognized by her peers who voted her Teacher of the Year after only briefly becoming a teacher. Her commitment to serving students, working collaboratively with coworkers, and dedication to the community made her a valuable asset within the district.
Dr. Chattman was chosen to serve in several areas while teaching including curriculum designer, professional learning facilitator, and director of the after school program. Soon thereafter, she was appointed Assistant Principal of Laurel Ridge Elementary, where she served, thrived, and helped improve the performance of the school for three years. Under her guidance the administration established a culture of inclusion, increased students’ performance, and empowered the staff to reach their full potential. Due to the successes that she was able to achieve at Laurel Ridge she was appointed Principal at Evansdale Elementary. At Evansdale she was responsible for 600 students, 81 staff members, and another opportunity to make a substantial impact in the lives of students.
Dr. Chattman alongside her team, was able to transform Evansdale Elementary into one of the highest performing schools in one of the largest school districts in Georgia. Recognizing and celebrating the diversity of the student population, several programs were implemented in order to meet the individual needs of students. She developed one of the first dual-language programs in Georgia, implemented a STEM program, which then led to an AdvancED STEM certification. Dr. Chattman’s efforts led to a significant increase on the state report card index and Evansdale became a Title I Reward School as well as becoming the first STEM-French Immersion school in the country.
Dr. Chattman has been a part of the leadership team at the Universal American School of Dubai since 2018 as Elementary Principal. Her accomplishments over the past couple of years were recognized and she has recently been given an additional role of Deputy Director. She is committed to the relentless pursuit of the vision of UAS to become the leading American International school in the region. She believes in the mission of nurturing a community of integrity and academic excellence. She looks forward to facilitating the values of belonging, curiosity, resilience, and empathy. In these coming years, she plans to continue to be a dedicated, strong, and beneficial leader for the UAS community.

Outside of school duties as an administrator, David enjoys playing sports (especially soccer and basketball), exercising, and going to the beach.

Originally from New Orleans, Louisiana, Sabrina completed her Bachelor’s Degree at Louisiana State University and received her teaching certification in the state of Texas before going on to earn her Master’s Degree from West Virginia University. She spent five years teaching at public schools in Texas and Louisiana before embarking on her journey in international education. Her first destination was Abu Dhabi, where Sabrina joined the American International School in Abu Dhabi (AISA) and developed an appreciation for the PYP philosophy of teaching and learning.
