Executive Director's Message
A Message from the Executive Director
Hello. I am Oh Seong-gook, Founder and Director of GCM Academy. To every parent and athlete who has found their way to us, thank you from the bottom of my heart.
I believe tennis is more than a sport — it is a great education that becomes the strongest nourishment for life. Within a community of athletes with clear goals, children build endurance and fighting spirit beyond their limits, a professional mindset that stays steady in victory or defeat, and the self-discipline and good attitude to govern themselves. The honest sweat shed on court becomes the foundation of a whole-person education that builds character.
Many parents, driven by a vague anxiety about the future, end up pushing their children. GCM Academy will carry that heavy burden for you. Admissions strategy, career worries and coaching are handled by our specialists — including veteran North American admissions officers — and together with specialized U.S. admissions institutions we prepare scholarship and university roadmaps from Plan A onward. At home, please give only warm love and encouragement.
Because a child's future is never decided by a single possibility or a single result, we make sure that learning never becomes pressure or stress.

Testimonial
아이의 꿈에 방향을 더해 준 GCM 테니스 아카데미
초등학교 1학년 말, 아이가 엘리트 선수로서 테니스를 시작했을 때, 저는 아이가 반드시 세계적인 프로 선수가 되기를 꿈꾸며 큰 기대를 품고 있었습니다. 하지만 시간이 흐르면서 세계적인 프로 선수라는 막연한 꿈은 구체적인 선수 진로에 대한 고민으로 이어졌고, 중학교 1학년이 된 지금은 ‘이 테니스 성적으로 대학에 진학할 수 있을까?’라는 현실적인 고민까지 하게 되었습니다. 꿈을 향해 달려오는 동안 기대와 희망만큼이나 걱정도 커졌고, 때로는 ‘이렇게 어려운 테니스 여정을 시작한 것이 맞는 선택이었을까?’ 하는 회의감이 들기도 했습니다. 아이의 꿈을 실현해 주고 싶다는 마음 하나로 다른 지역으로 이사하고, 여러 아카데미를 옮겨 다니기도 했습니다. 그러다 보니 어느새 아이의 삶뿐만 아니라 가족 모두의 일상이 테니스를 중심으로 돌아가고 있었습니다. 아이가 주체적으로 자신의 삶을 꾸려 가기보다는 테니스에 맞춰진 삶을 살아가고 있다는 생각이 들었습니다. ‘정말 여기는 다를까?’ 하는 마음으로 GCM 테니스 아카데미에 일일 훈련을 신청하고 코치님들과 이야기를 나누게 되었습니다. 일일 훈련을 통해 아이를 지켜보고, 코치님들과 여러 이야기를 나누는 과정에서 아카데미 운영에 대한 열정과 확고한 교육 철학, 그리고 아이들의 미래를 바라보는 시각을 접할 수 있었습니다. 특히 훈련 후 코치님께서 해 주신 말씀들이 제 마음에 깊이 와닿았습니다. 그동안 제가 아이의 테니스 실력과 성과에만 집중한 나머지, 정작 아이의 미래를 위해 필요한 환경이 무엇인지 충분히 고민하지 못했다는 것을 깨닫게 되었습니다. 무엇보다 코치님들의 말씀을 통해 테니스를 잘하는 것 자체가 최종 목표가 아니라, 테니스를 통해 아이가 어떤 사람으로 성장하고 어떤 미래를 만들어 갈 수 있을지 함께 고민하는 것이 중요하다는 생각을 하게 되었습니다. 그리고 그 방향성에 대한 확신이 생겼기에, 저희 가족은 고민 끝에 GCM을 새로운 터전으로 과감히 결정하게 되었습니다. GCM은 단순히 테니스 실력을 향상시키는 것을 넘어, 아이가 다양한 경험을 통해 성장하고 더 넓은 미래를 설계할 수 있도록 전문적인 환경을 만들어 주고 있었습니다. 다양한 외부 캠프와 활동은 물론, 테니스 선수로서 성장하는 길과 테니스를 적극적으로 활용해 미래의 다양한 진로를 만들어 갈 가능성까지 함께 고민해 주신다는 점이 특히 인상 깊었습니다. 그동안은 ‘무조건 테니스를 잘해야 한다’는 생각에 집중했다면, 이제는 ‘나의 미래를 위해 어떤 방향으로 테니스를 잘해야 할까?’, ‘나는 어떤 선수로 성장하고 싶으며, 나만의 브랜드와 정체성은 어떻게 만들어 갈 수 있을까?’라는 질문을 아이 스스로 고민하게 되었습니다. GCM을 통해 테니스를 바라보는 시야가 넓어졌고, 선수로서 자신만의 방향성을 찾아가는 법을 조금씩 배워 가고 있습니다. 무엇보다 감사한 것은 아이의 변화입니다. 이전에는 단순히 테니스 기술을 익히고 경기력을 높이는 데 집중했다면, 이제는 자신이 어떤 이미지의 선수로 성장하고 싶은지, 나만의 브랜드를 어떻게 만들어 갈지 고민하기 시작했습니다. SNS에 게시물을 올릴 때도 자신의 모습을 좀 더 신중하게 돌아보고, 테니스뿐만 아니라 학업과 다양한 활동을 통해 자신만의 모습을 만들어 가려는 모습이 보입니다. 아이가 단순히 운동을 잘하는 선수를 넘어, 자신의 가능성을 주체적으로 고민하고 미래를 준비하는 사람으로 성장하고 있다는 점에서 코치님들께 진심으로 감사한 마음입니다. 테니스라는 하나의 목표에 아이의 삶을 맞추는 것이 아니라, 테니스를 통해 아이의 삶이 더욱 풍성해질 수 있다는 것을 조금씩 알아 가고 있습니다. 아직 중학교 1학년인 아이에게는 앞으로 많은 시간이 남아 있습니다. 지금의 꿈이 더 구체화될 수도 있고, 새로운 방향으로 바뀔 수도 있을 것입니다. 중요한 것은 어떤 길을 선택하든 아이가 스스로 가능성을 발견하고, 자신의 미래를 주체적으로 그려 나갈 수 있는 힘을 갖는 것이라고 생각합니다. GCM에서는 아이가 다양한 가능성을 경험하고 자신만의 방향성을 찾아갈 수 있는 환경을 만들어 주실 것이라는 믿음이 생겼습니다. 테니스라는 하나의 목표를 넘어 아이의 더 넓은 미래를 함께 고민할 수 있게 되었다는 것, 그리고 그 미래를 다시 희망적으로 그려 볼 수 있게 되었다는 것이 학부모로서 가장 큰 변화입니다. 아이의 성장을 위해 늘 고민하고 노력해 주시는 GCM 코치님들께 진심으로 감사드립니다. 앞으로 아이가 GCM과 함께 어떤 모습으로 성장해 나갈지 기대하며, 저희 가족도 아이의 가능성을 믿고 한 걸음씩 함께 걸어가고자 합니다.

ParentMay tennis become a path that widens my child's possibilities.
Our child has been training and growing at GCM for three years. At first, I thought that since my child loved tennis and wanted to be good at it, all we needed was to meet a good coach, train hard, and gain match experience. But as the athletic journey continued, I came to realize that tennis is a sport requiring far more choices and strategy than I had imagined. Above all, an athlete ultimately needs "results." You have to prove your potential in matches, and to move up to the next stage you also need objective outcomes such as tournament results and rankings. If you are preparing for a wider stage, you must build your competitiveness not only in domestic tournaments but also within international standards like UTR and ITF. Because of that, a parent's heart is always conflicted. Is now the time to gain more match experience, or to build more skill and fitness? Should we value immediate results, or wait for a few years down the road? Training is necessary for good results, but I worry whether too much of it will exhaust my child's body and mind. Results are needed, but you can't chase results alone; you must train a lot, yet you must not burn the child out. That has been my greatest worry over this time. In the beginning, I thought that I, as the parent, had to research more and get more involved to guide my child well. There were moments when my heart wavered and I grew impatient depending on match results. But over three years with GCM, my thinking gradually changed. The ones who meet my child on the court every day, who have watched both their strengths and shortcomings, are the coaches. They have been there not only for the good moments but also for the moments when eagerness got ahead, when my child wavered in matches, and through the process of repeating the same mistakes. So at some point, rather than trying to find all the answers myself, I decided to trust the coaches' experience and strategy. And with that, my worries changed too. From "How good a player will my child become?" to "What kind of person will my child grow into through tennis?" Tennis was not a sport of technique alone. The power to settle one's emotions after a point ends, the power to judge for oneself in crucial moments, and the attitude of accepting defeat, admitting one's shortcomings, and training again all these were abilities an athlete needs. In the end, I came to believe that raising a child who can create results for themselves is more important than creating the results for them. Looking at the training direction GCM offers with these thoughts in mind, the things I considered important came into clearer focus. They assess the athlete's current level (Assessment), design training to match it (Training Design), apply it in real matches (Match Application), and analyze the match content and data again (Performance Review). Based on those results they design the way forward (Pathway Planning) and move on to the next stage (Next Level). I especially resonate with the fact that training does not end as mere training. Playing well in practice and delivering your own tennis in a match are different things. I believe that when the process of trying trained skills in matches and bringing the problems found in matches back into training is repeated, a child can grow beyond simply hitting the ball well into an athlete who understands their own game. And now my thoughts extend beyond the court as well. How to balance academics and English while continuing tennis, how to build international experience through UTR and ITF, and how to balance studies and tennis going forward. I hope that by training enough and experiencing diverse competition while also preparing academically, several doors will be open for my child when the day comes to decide their own future. That is why I believe an athlete's growth is not built alone. The athlete, the coaches, the parents, and the people who look together at academics, careers, and a wider future beyond the court a team where each person, in their own place, looks in the same direction. If the past three years were a time of building trust in the GCM coaches, I now look forward to the next chapter growing into a team that, on top of that trust, looks after my child's tennis, academics, and career path together. I too want to be a parent who does not decide everything on my child's behalf, but who trusts and supports the coaches' expertise and judgment, and who, in my own place, helps my child walk their own path without burning out. Building enough skill and experience, a good environment, and good people around them so that one day they can choose their own path that, I believe, is the role I must play. May tennis be not a path that limits my child's possibilities, but a strength that carries them out into a wider world. I trust and support the GCM coaches who have run on the court alongside my child for the past three years. And I look forward to what GCM will become next as good people, standing on the trust built so far, come together as one team. Our family, too, as one member of that TEAM, will share in our child's today and prepare for what comes next with an excited heart. 🎾

ParentOur Connection with GCM
Our child attends school in Jeju, so they come to GCM to learn tennis during vacations or while staying in Seoul. My child is not majoring in tennis or aiming to become a professional, but through steady practice they have even competed as a school representative in matches against other schools and achieved good results. What I have always been grateful for at GCM is that they don't look only at a child's skill level. Compared with the children training as athletes there are many areas where my child falls short, but rather than letting that become discouragement, the coaches encouraged my child to challenge themselves a little more from where they stand and to see things through to the end. They value process, attitude, sincerity, and responsibility over results, and even though my child only visits during vacations, they remember my child's temperament and changes and look after them attentively. As a parent, trust naturally grew. Recently I heard that GCM was starting tennis consulting, and at first I received a one-time session. Since I had received consultations about admissions or tennis elsewhere before, I went in without great expectations, simply wanting to hear some advice about the direction ahead. But after the consultation, my thinking changed a little. It was not focused only on "how to get better at tennis," or "which tournaments to enter and what results to produce." Instead, they considered my child's academics, school life, and even the possibility of studying at a university abroad all together, thinking about which direction to carry tennis forward. What especially touched me was that, rather than a plan to produce immediate results, they were thinking about a direction in which my child could keep growing steadily over the coming years. For my child, who is not aiming to be a professional, they thought together with us about what tennis could mean, how to balance academics and sport, and how to meaningfully carry the tennis done so far into future school life and the path to higher education. In the end, I came to feel that good consulting is not about fitting a child to some result, but about looking at what kind of person that child will grow into and building a long-term roadmap together. A place that, beyond teaching tennis, considers a child's possibilities and future together. For our family, GCM is now becoming exactly that kind of dependable partner.
