Reedley International School was founded by Nellie Aquino-Ong in 1999. The name was bestowed as a tribute to Reedley College, California, USA, a small community where Mrs. Ong studied and excelled along with the help of nurturing teachers and mentors. After his success in the Gold Rush in the 1800s, Thomas Law Reed donated the land to the community and the town became known for its excellent nurturing of fruit harvests. This value of nurturing was evident among teachers and administrators in Reedley College and is seen today in Reedley international School.
Starting life as a review center to give personalized teaching to students aiming to enter the country’s top universities, Reedley opened as an Upper School in 2000, with 80 students. A 250% growth rate in 2001, and the opening of Grade School and Middle School, saw Reedley move to larger premises in Pasig. In 2006, Reedley moved to its current location in Libis, Quezon City, to cater to the current level of 523 students from 19 different nationalities.
