Meet Esmarie Carstens
– educator, school builder, professional photographer, gardener, baker, and firm believer that life is better with a bunny nearby.
Esmarie has been part of Tate International School’s journey since the beginning as one of the school’s founding teachers. Having studied Psychology, she worked alongside founding members Nikki and Lieze as a learning support specialist and private facilitator, bringing deep insight to her work with students.
With a deep passion for understanding children, their individual circumstances and what shapes the way they learn, Esmarie has always held a strong belief that every child can learn. She is passionate about creating an environment where learners feel understood, supported and confident in their ability to grow.
A strong advocate for digital learning, Esmarie completed a certificate in Instructional Design through WITS and led the development of the Tate World project, strengthening interactive learning and the use of technology across the school. Today, she leads Tate with the same belief that started it all, that school should be a place where children can learn, grow and thrive.
Outside of school, Esmarie is a professional photographer, enthusiastic gardener and keen baker. She loves creating beautiful things, getting her hands dirty in the garden, and believes that most problems can be made considerably better with a bunny, because, really, who needs therapy when you have a bunny?
Operations Manager
Meet Erin Vockerodt
At Tate, Erin is the behind-the-scenes powerhouse who keeps the wheels turning and the chaos under control. As our go-to Operations Manager, she’s the one making sure events happen, resources appear like magic, and everything runs like clockwork — all with a big smile and a “let’s do this” attitude.
With a Diploma in Tourism and Tour Operations and over two decades of high-energy experience (including a stint in London’s wild restaurant scene!), Erin knows how to manage people, pressure, and a hundred moving parts — and still make it look easy.
She also happens to hold a Silwood Cordon Bleu Diploma and leads Tate’s popular cooking classes, where kids get hands-on with food, fun, and flavour. Whether she’s hosting fundraisers, fixing the unfixable, or firing up the ovens, Erin brings heart, humour, and a whole lot of hustle to school life.
Finance Manager
Financial & HR
Meet Nika Swanepoel
– the warm heart behind Tate’s finance desk and the gentle force keeping school fees on track. With a BCom background and over 15 years in admin (six of those in finance), she brings serious know-how with a smile. Her journey began as an autism tutor and au pair, where she spent 13+ years supporting wonderfully unique kids — and that care still shines through in everything she does.
Far from her biological family, Nika’s found a true home at Tate, where connection and community mean the world. You’ll often find her with Pixel, her tiny four-legged sidekick, trotting along beside her and winning hearts.
Numbers may be her job, but people are her passion. As Nika likes to say, “I am what I am” — and honestly, we wouldn’t have her any other way.

Meet Carine Geldenhuys
– fitness lover turned educator and the go-to for sports, structure, and organisation at Tate.
Starting with a passion for movement and health, Carine studied at ETA before discovering her true love: working with kids. She joined Tate as Aftercare Manager, then quickly took on roles as PE Teacher and Assistant Teacher across Tate World and Tate International.
Now, Carine is the Sports and Extra-Mural Coordinator while teaching Afrikaans (Grade 4) and English and Geography (Grade 7) — plus running after-school sports for both Primary and High School.
She’s currently studying for her Bachelor of Education (BEd), always leveling up her teaching game. When not working, you’ll find her hiking or colour-coding — because yes, she’s a bit of an organisation nerd!
Carine loves being part of the Tate family and treasures watching her students grow and thrive every day.

Meet Dané Meier
– lover of picture books, outdoor adventures, and all things early learning! With a degree in Foundation Phase Teaching, Dané has been inspiring little minds since 2021. At Tate International School, she brings creativity, care, and calm to the Grade 1 and 2 classrooms, creating a space where curiosity grows and every milestone is celebrated.
Dané is also part of the Curriculum Development Team, helping craft meaningful learning experiences across the school. She’s all about meeting each child where they are and guiding their growth with patience and heart.
When she’s not in the classroom, you’ll likely find her curled up with a good book or recharging in the great outdoors. Dané loves being part of the Tate family, where every child and every teacher matters.

Meet Dr Irene Sealiete
– calm, friendly, structured, and the person you want around when someone says, “Let’s see what we can do in the lab.”
Dr Irene Sealiete brings an impressive academic background to Tate, but it is her calm and thoughtful approach that really stands out. She has a natural ability to make students feel comfortable while encouraging them to understand, question and think critically.
Irene began her academic journey with a Bachelor of Science, followed by a Postgraduate Diploma in Education (PGDE), a Postgraduate Diploma in Chemical Engineering, a Master’s degree in Chemical Engineering, and most recently, her Doctorate. She teaches Chemistry and Biology at Tate and has experience teaching at both school and university level.
With her strong scientific background, Irene is particularly at home in the laboratory, where ideas can move from something on a page to something students can actually explore and investigate.
Friendly, professional and wonderfully calm, Irene brings both expertise and a steady presence to the Tate teaching team.

Meet Jessica Grobler
– fun, grounded, full of heart, and probably already knows your child’s favourite joke, snack and exactly when they need a little extra support.
Jessica Grobler brings warmth, strong values and plenty of personality to the Tate team. She works hard, knows what she wants, and brings that same determination into the way she supports our students.
Currently studying Foundation Phase Education through STADIO, Jessica works across a variety of primary school grades as a teacher’s assistant. Her real strength is connection, she steps into each child’s world, gets to know their humour, interests and quirks, and builds the kind of trust that helps them feel comfortable enough to learn.
Hardworking, loving and always up for a laugh, Jessica brings heart, energy and a genuine understanding of our students to Tate and we wouldn’t have it any other way.

Meet Mariëtte Horne
– artist, language lover, and storyteller with a heart full of passion and a paintbrush never far from reach.
Mariëtte began her journey in Journalism at the University of the Free State, but quickly found her true calling in the classroom. Since 1979, she’s been sharing her love of Afrikaans, art, and learning with students across South Africa.
She’s held roles in education, media, and even co-ran an architectural studio, all while following her creative instincts — from studying Monet in Paris to exploring Tintoretto’s works in Venice.
Mariëtte joined Tate International in 2020, where she now teaches Afrikaans and Art with a signature blend of warmth, colour, and care.
She’s a proud horse lover, a forever student, and deeply believes that every child deserves an inspired education — and a teacher who never stops learning herself.

Meet Timothy Chimedzi
– number cruncher, deep thinker, and all-around learning enthusiast. With over 10 years in education, he brings experience, energy, and a real passion for unlocking student potential. He holds a Master’s in Finance and Investments, and is currently juggling a BSc in Applied Mathematics and Computer Science and a PhD in Finance— because why stop at one degree?
At Tate International, Timothy teaches Mathematics and Physics at IGCSE and AS Level, where he turns complex concepts into lightbulb moments. His goal? To spark curiosity, build confidence, and help students see beyond the formulas.
Outside of class, Timothy is a lifelong learner who loves coding, reading, and a good game of football. He believes every child has their own kind of brilliance — and he’s here to help them find it.
He’s proud to be part of the Tate family, where learning is bold, personal, and full of possibility.

Meet Sadé Kapp Potgieter
– our dedicated Grade 6 teacher and Grades 7–8 Mathematics teacher.
Sadé holds a Financial Degree, a BEd in Intermediate and Senior Phase, and a TEFL
diploma. With twelve years of teaching experience across a variety of schools, she brings depth, passion, and professionalism to her classroom.
A devoted animal lover, Sade volunteers at local shelters and shares her home with four energetic dogs who keep her days bright and lively.
Sport, fitness, and the outdoors are also big parts of her life. She has earned both Western Province and South African colours and enjoys dancing, training, hiking, and exploring nature whenever she can.
Known for her positivity and zest for life, Sadé brings warmth, energy, and a sense of
adventure to the Tate community — and to every learner she teaches.

Meet Tamarin Rose Philpott
– passionate educator, child advocate, and proud Grade 5 teacher at Tate International School.
With a BA in Social Work from UCT and an Honours in Theology from the University of Pretoria (with a focus on vulnerable children), Tamarin brings a deep understanding of emotional wellness and child development to her teaching. She’s also SACE-registered, bringing both care and compliance to the classroom.
Before joining Tate in 2021, she worked as a guidance counsellor at Edgemead Primary and other schools, shaping her warm, empathetic teaching style. At Tate, she’s taught Grade 4, contributed to curriculum design, and now leads Grade 5 with heart and purpose.
Tamarin is all about creating a space where kids feel safe, seen, and inspired to grow. Outside of school, she’s into crime series, yoga, and keeping life balanced — just like she does in the classroom.

Meet Thomson Chilomo
– tech whiz, history lover, and all-round classroom favourite at Tate International School.
Thomson teaches IGCSE Computer Science and History, combining storytelling with problem-solving to keep lessons engaging and relevant. From decoding algorithms to unpacking revolutions, he’s all about turning tricky concepts into lightbulb moments.
Before joining Tate, Thomson worked as a Cybersecurity Lecturer at Eduvos and an IT Trainer at CTU Training Solutions, giving him hands-on experience and a strong, student-focused approach. Thomson is currently pursuing a Master’s in Computer Science, expanding his expertise in Coding, Big Data, and Artificial Intelligence to bring cutting-edge skills into the classroom.
Outside the classroom, Thomson’s often found sketching, exploring historic spots, or tinkering with code, all part of his passion for lifelong learning.
At Tate, he’s known for being approachable, curious, and deeply committed to helping students grow — one clever question at a time.

Meet Keagan van Staden
– patient, creative, encouraging, and the person you want around when a child says, “I just don’t get it.”
Keagan van Staden brings a warm, thoughtful approach to Tate, with a genuine desire to understand how each child learns best. Having already worked with some of our students before joining the teaching team, we have seen first-hand the positive impact of her patient and individualised support.
As the founder of The Literacy Grove, Keagan has supported children through personalised learning programmes in literacy, numeracy and homework support. She also brings valuable Foundation Phase experience, including individual student support and small-group instruction.
With specialised training in the Colour Reading Programme and the Orton-Gillingham approach, Keagan is especially passionate about helping children build strong literacy foundations through structured, multisensory learning, turning “I can’t do this” into “I’m starting to get it.”
Friendly, creative and deeply invested in her students, Keagan brings both skill and heart to the Tate team, and we are excited to have her guiding our Grade 3 learners.

Meet Leeze Myburgh
– the teacher who somehow always has a bag full of solutions, ideas, and probably something useful for whatever problem you’ve just brought her.
Leeze is no stranger to Tate, and we’re thrilled to have her back. She brings energy, initiative and a genuine willingness to get stuck in wherever she is needed; whether that’s in the classroom, on the Academic Development Team; or helping bring a school production to life.
With a background in Psychology, Early Childhood Development and a Postgraduate Certificate in Education (PGCE), Leeze has taught learners from Grades 6 to 9, specialising in Mathematics and Science. She now teaches Secondary Phase Sciences and Grade 8 Mathematics at Tate.
Outside of school, Leeze is happiest surrounded by animals and nature. She lives on a farm, where her animal family includes bunnies, cats and even an amphibian baby, so it’s safe to say her classroom isn’t the only place where she gets to work with a diverse group!
Leeze brings warmth, creativity and plenty of ideas to everything she does, and we’re very happy to have her back in the Tate family.

Meet Shanay Nothard
– calm, creative, and the teacher who somehow always has a new project on the go.
Shanay is a natural when it comes to working with students. She takes the time to listen, understand them and meet them where they are, creating a calm and supportive space where learners feel comfortable being themselves.
With a Bachelor of Education from the University of the Western Cape, specialising in English and Mathematics for the Senior and FET phases, as well as a 120-hour TEFL qualification, Shanay brings a strong academic foundation to her teaching. She loves finding creative ways to make learning meaningful and engaging.
And when she’s not teaching? You’ll probably find her with a ball of yarn in her hands! Shanay runs our Yarn Club and is wonderfully creative, making her own jerseys, bags and all sorts of other things.
Her calm nature, creativity and genuine ability to connect with students make Shanay a wonderful addition to the Tate team.

Meet Marike Smuts
– class assistant, admin multitasker, LMS whiz, and all-around nature-loving, child-championing wonder woman.
Marike has been part of both Tate World and Tate International since 2022, officially wearing multiple hats (and rocking every single one). She’s a Class Assistant, Tate World Administrator, and Learning Management System Operator — and yes, she built online lessons all the way back in 2020 like a total behind-the-scenes hero.
But Marike’s magic goes far beyond the screen. Her day-to-day includes gardening, Arts & Culture, PE, and after-care, bringing calm, creativity, and connection to every corner of the school.
She’s got a heart full of empathy, a deep love for children and animals, and an energy that’s equal parts nurturing and down-to-earth. Whether she’s planting seeds (literal or metaphorical), leading an art session, or simply lending a listening ear, Marike’s presence is always one of warmth and patience.
Being part of the Tate family is a true joy for her — a place where she gets to watch young minds grow, express themselves, and bloom in the most creative ways.

Meet Christina Mokwena
– the heart and soul behind the calm and care in our school!
More than just a custodian, she’s like a mother to everyone in the halls, always watching out for the little things that make a big difference. Whether it’s tidying up, offering a comforting word, or making sure every corner feels safe and welcoming, Christina’s gentle presence is a steadying force for all of us.
No mess is too messy, no problem too small — she’s always there with a warm smile and an open heart. We’re truly lucky to have her nurturing spirit keeping our school feeling like a home.

Meet Veronica September
– the quiet hero of our hallways and classrooms!
Whether it’s a spill in the science lab, a missing mop, or a mysterious squeaky door, she’s there when we need her — often before we’ve even asked. Always ready to lend a hand (or a broom), she keeps our school running smoothly with a smile and a can-do attitude.
No task is too big, no corner too dusty. We’re lucky to have her as part of the team — because every school needs someone who makes the behind-the-scenes magic happen!
