St George the Great Martyr Church began as a Mission of the Orthodox Church in America in 1979. The present land it occupies was purchased in 1980, and the ground was broken for the Church building in 1981. The first services were held in the church in 1982, with the founding Rector, Fr. John Reeves, officiating.
The Mission was granted Parish status by Archbishop Dmitri in 1994. Under Fr. John's leadership, the parish hall was completed in 1986. Since its inception, St. George Church has hosted two Diocesan Assemblies; one held in July 1985 and one in July 1995. Fr John left for another assignment in early 1996, and Fr Aaron Archer took over as Pastor in July of that same year. After Fr. Aaron's retirement in mid-2001, Fr. Antonio Perdomo was assigned to St. George's Parish in January of 2002 and served until his repose in April 2021. Fr. Antonio was a native Spanish speaker and had been able to reach out to those who speak Spanish on both sides of the border.
As the only Orthodox Church serving the lower Rio Grande Valley, St. George is blessed to minister to an ethnically and culturally diverse population including members and visitors from Mexico. All visitors and guests are welcome, especially families with children and Winter Texans who enjoy spending the winter months in the tropical climate of south Texas.
