Steps to Finding and Meeting with College Alumni
1) Talk to every adult, friend, brother or sisters of friends to learn who knows alumni of the colleges to which you are targeting for admission. Make appointments to meet with them to discuss your interest in their alma mater. Everyone has resources and connections. Use your network -- everyone -- that you know and ask them if they know anyone that graduated from the colleges you are considering.
2) You can also contact the admission office of the colleges as well to get lists of alumni who have given their office permission to give out their names and contact information for students like you who are considering their campus.
3) Attend college fairs at your high school or in the surrounding area. Admissions officers cannot attend all the college fairs in the country, they utilize their alumni networks to man or woman the tables at the fair. Asking at the table for some of their time either at the fair or afterwards to answer your questions, this is an instant connection, adding them to your list of contacts for the schools you are interested in.
4) Meeting with alumni and referencing these meetings can add to your application. It shows a higher predictability of your attending if they admit you. Colleges today are looking for every way to predict if you would attend if they admit.
