Dia Gerontoudi Prep Center is a must when it comes to Grad School applications preparation. The Center is truly student focused – methodologies and tactics are customised according to each student’s strengths and weaknesses, forming the basis for success. Dia and Thomas, with whom I had the chance to work with, are very charismatic, experienced and results oriented. I fully recommend it!
