Ιστορίες Επιτυχίας

Receiving acceptances from universities from the US and the Netherlands was one of the greatest moments of my life. I owe part of that success to the Dia Gerontoudi Prep Center.

Dia Gerontoudi and her team were pivotal in my GMAT prep and INSEAD admission. Under Dia’s guidance, I reached the 94th percentile in Verbal—her focus on interpreting context and reasoning instead of rote learning changed how I approached the test. She pushes you with intention and care.

The Dia Gerontoudi Prep Center is far more than just another test prep center. It is a world-class institution dedicated to excellence, committed to meaningfully preparing and mentoring students to succeed in the most demanding academic environments.

Looking back, two years ago when I began exploring and preparing for Master’s programs, I knew the journey wouldn’t be easy. However, today I can confidently say that choosing Dia Gerontoudi Prep Center was one of the best decisions I made, as their support made the whole process much easier and more manageable.

I wholeheartedly recommend the Dia Gerontoudi Prep Center to any student aspiring to study abroad. The center’s commitment to academic excellence and personalised support are of the highest standard and have played a crucial role in my academic success.

I owe so much to Dia Gerontoudi Prep Center and the incredible people who work there. They didn’t just prepare me for exams—they helped shape my future. I wholeheartedly recommend them to anyone looking for not just top-tier preparation, but also genuine support and encouragement along the way.

When I first set out on my GMAT preparation journey, I knew the road ahead would be challenging. However, what I did not expect was to find a team of educators who would not only guide me through the complexities of the exam but also inspire me in ways that extend far beyond the classroom.

During my preparation for an MBA in the USA, I worked closely with both Dia Gerontoudi and Thomas Kalandranis. For her part, Dia was much more than a great teacher. She was a real mentor! Her perfectly organized method (class courses and labs) enabled me to identify my weaknesses and improve on them, in order to excel at the GRE/GMAT and TOEFL exams.

As a person with an engineering background, I sought help with the verbal section for the GMAT exam. I, therefore, embarked my MBA preparation journey by reaching out to Mrs. Dia Gerontoudi, who effectively guided me and helped me significantly boost my Verbal scores. In the end of our sessions, my Verbal score outperformed my GMAT Quant result (self-taught), a testament of the great support, tips and tricks and teaching effectiveness provided by Mrs. Gerontoudi – for which I am very grateful.

Applying to the top US Law Schools can be quite challenging. Thanks to Mr. Thomas Kalandranis guidance, I achieved a high TOEFL score, which opened the doors to top US Universities.

I’m excited to share my journey to the Master’s in Real Estate Economics and Finance at the London School of Economics (LSE), and I owe so much of this achievement to the incredible mentorship and support I received along the way. Without the guidance and belief of those who helped me, I’m certain this dream wouldn’t have become a reality.

I cannot express enough how grateful I am for Dia Gerontoudi Prep Center. Dia and Thomas are not just outstanding tutors who prepare individuals for the most competitive programs—they are true mentors who have profoundly shaped my journey.

I embarked on my MBA preparation journey with Dia Gerontoudi Prep Center in January 2023, initially enrolling in GMAT and IELTS classes. However, Ms. Gerontoudi and Mr. Kalandranis quickly became much more than just instructors—they were pivotal mentors throughout this challenging and often emotional process. Their unparalleled guidance and support helped me navigate every stage, from selecting the right U.S. universities that aligned with my goals to meticulously preparing for the GMAT, IELTS exams, and interviews.

I am thrilled to write this recommendation for Dia Gerontoudi Prep Center. As a recent admit to the Master’s program in Project Management at Boston University, I can confidently say that the exceptional guidance, resources, and unwavering support I received from this center were instrumental in my success.

It may sound like a cliché, but it is absolutely true that without the catalytic assistance of Dia and Thomas, this magical journey that lies ahead of me would never have become a reality.

Thomas’ method not only equipped me with essential exam skills but also nurtured a critical mindset, allowing me to decipher the true essence behind each exam question. Beyond the classroom, I forged connections with other bright-minded students who have become lasting companions. Dia Gerontoudi Prep Center is, without a doubt, the ultimate destination for anyone serious about excelling in their IELTS exam.

Mrs. Dia Gerontoudi is a person who truly cares about her students. Her approach helped me not only with the GMAT test but also with building a way of thinking which helps me even in my everyday life. I understood clearly that she is not just a teacher, but an academic with a gift to maximize the potential of her students. I cannot express how highly I recommend Dia Gerontoudi Prep Center for anything that has to do with university applications and GMAT preparation.

Applying for graduate programs is undoubtedly a draining process and the importance of having the right allies along the way simply cannot be overstated. For me, the right allies were Dia Gerontoudi and Thomas Kalandranis.

Having worked with Dia Gerontoudi and Thomas Kalandranis before on the GRE exam and on M.Sc. admissions, Dia Gerontoudi Prep Center was the obvious choice when I started thinking of GMAT and applications to MBA programs.

Applying for a Master’s degree to some of the most prestigious universities in the world is truly a life-changing decision. I realized that the key to achieving my goal would be selecting a team with a high level of professionalism and a strong work ethic.

The instruction I received by Mrs. Gerontoudi throughout my preparation for the verbal and written section of the test was consistently insightful, highly personalized, and, most importantly, to the point.

My admission to Georgetown University became possible thanks to the invaluable assistance provided by Mr. Thomas Kalandranis and the Dia Gerontoudi Prep Center.

Applying to the Ph.D. program at the most prestigious engineering universities in the world is definitely a stressful and tough task as they demand a nearly perfect score on TOEFL and an exceptional personal statement.

If you’re aiming to pursue your master’s at a competitive university, Dia Gerontoudi Prep Center is the ideal place to ensure you will receive the proper guidance and materials to achieve your goal. Mr. Kalandranis assisted me with my TOEFL preparation, leveraging his experience to help me attain my desired score within the timeline I had set.

I contacted Dia Gerontoudi Prep Center on the strong suggestion of a good friend, intent of aiming for a top MBA program in the USA. Honestly, I was a little concerned about whether the scale of my ambitions and dreams was in fact too much for my abilities.

Dia Gerontoudi Prep Center played a pivotal role in my successful application process for the Masters in Financial Analysis (MFA) program at London Business School…I am immensely grateful for his mentorship, and I have no doubt that his expertise and dedication will continue to empower the journeys of many aspiring candidates.

Dia Gerontoudi is undoubtedly the best prep center for university preparation in Athens. My experience with other prep centers has not been exactly pleasant. I first met Mr. Thomas Kalandranis to seek help for the TOEFL exam preparation. He immediately helped me to build confidence on the Speaking Section, enhanced my knowledge of the English language and the skills required from the exam, and informed me in a very detailed way over the testing process, which was extremely important for the final outcome. I also attended classes for the IELTS exam, in order to apply for postgraduate studies of Architecture in the UK, with a positive IELTS score of 7.5.

Preparing for the GMAT can be challenging for many, due to the time and effort it requires, as well as the unfamiliarity with the type of questions asked. Mrs. Gerontoudi played a pivotal role in my accomplishment. Her teaching approach is strategic, recommending specific methods for different question types and sharing time-saving tips that proved invaluable during the exam. In addition, the material and exercises she provides are more than adequate, as they cover all kinds of questions that could possibly be encountered in the exam.

Dia Gerontoudi Prep Center was the best choice for anyone who wants to get accepted from competitive universities, in my case in Dentistry. I started my preparation for GRE and TOEFL and I was really content with my performance.

His methodical approach, pertinent advice and insightful expertise gave me a significant advantage. Against the backdrop of a demanding year, our virtual meetings provided me with the clarity I needed to streamline the various work streams of the application process. Owing to Mr. Kalandranis’ thorough understanding of the US universities, I was able to showcase my strengths in the most favourable light.
