“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. However, my greatest gain from working with Dia was her mentoring. Thanks to her, I managed to clarify my goals, plan my future, and develop the required skills to face potential challenges.”

“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. One of the greatest difficulties in having to prepare for the GRE in a tight timeframe is to avoid wasting time on generic, pointless exercises and chaotic vocabulary lists. Assisted by her long experience with the test, aptitude for intuitive teaching, and vast supply of holistically designed practice material, Mrs. Gerontoudi is excellent in efficiently instilling the essential aspects of each subsection, and providing customized study plans based on the student’s past performance.”

“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. Working full-time, I had a solid math foundation, specific needs and very limited time, so I opted for private tutoring on the verbal part of GMAT with Dia and consultation sessions with Thomas.”

“As one scrolls down this list, one can’t help but be impressed by the success stories of young people from all over Greece. Their journey towards their goal has been an accumulation of hard work, discipline, and a compelling narrative that made them stand out. I am filled with joy and humility to be included among them.”

“Working with the Dia Gerontoudi Prep Center was the single most important decision in my MBA journey and the key to getting into my school of choice.

I admit that I was a non-believer before I worked with them. I was confused when a number of friends (who haven’t lived in Greece for years) recommended the tutors at the Dia Gerontoudi prep center for an international exam in English.  So, I started my GMAT journey with a private tutoring package from a large international GMAT provider. A few weeks later, I phoned Mrs Gerontoudi and never looked back.”
