The college application process was very stressful for both my daughter and I. We started getting serious about University Preparation at the end of Sophomore year and found ourselves  way over our head with everything needed. We contacted Ariston and our daughter got the help she needed!


Ariston Elite Admission Services guided my daughter through every stage of the application process and helped her secure a place at all three business schools of her choice. Their incredible ability to cater to exactly what my child needed made all the difference in the world. We thank you from the bottom of our hearts!


Between preparing for standardized tests, reviewing her academics and extracurricular, finding ways to boost her candidacy and thinking about the college essays we found ourselves way over our heads. Luckily, a friend of mine’s son had started working with Demetra and after a wholehearted recommendation we decided to schedule the preliminary consultation. In just 20 minutes, Demetra Tzevelekos got an incredible feel for my child and managed to pinpoint our areas of growth and make a couple of crucial suggestions that would help my daughter’s application. We signed up with Ariston immediately and were touched!
