After attending the grammar school at Swansea, he entered around 1762 Carmarthen College, and became minister-elect of the church at Gellionen in 1764, while pursuing his studies at the College for two years longer. Rees was also, until about 1785, a successful schoolmaster. He became known as a preacher, and published some sermons.
His chapel was rebuilt and enlarged in 1801.
