Open Door Preschool was established in 1971 at Grace United Methodist Church in Old East Dallas. The school initially educated a room full of four-year old, Spanish speaking children. The Hispanic community, which had begun to populate the East Dallas area, treasured the preschool and its services. Soon, there was a waiting list for entry.
In the 1980s, a large influx of Asian families moved into the East Dallas area. Open Door Preschool expanded its services to meet the needs of this growing population. The presences of two language groups provided an additional incentive for the children to learn English. Only then could they communicate with each other.
In the fall of 1988, the school expanded to a second room, increasing its capacity to 36 children. In 1998, a third classroom was added, increasing its capacity to 46 students. Today, Open Door Preschool serves children from several different language backgrounds. Its maximum capacity is 55 students, and operates as a full-day, intensive educational facility.
