The first missionary field for the UAIM was Picalquí, in Pichincha, Ecuador, where the mission bought a farm to train the amerindian people living there in agricultural techniques. The mission also operated a small medical mission with the help of American physicians already living in the country. Later on, the mission expanded to other places, but it never gained a strong presence in Ecuador. When the mission disbanded (due to disagreements among its missionaries and also because of the strong anti-American feelings among Ecuadorian church leaders), it had few congregations. In 1965, its congregations and parishes merged with those planted by missionaries of the
Church of the Brethren, to form the United Evangelical Church of Ecuador (Iglesia Evangélica Unida del Ecuador or IEUE), which changed in 1999 its name to United Evangelical Methodist Church of Ecuador. The United Church's first president was Rev. Gonzalo Carvajal, who resigned to work for
HCJB and the
Presbyterian Church in America (PCA). Since the denomination adopted a Methodist identity, it has an episcopal structure. The current presiding bishop is Silvio Cevallos Parra. ==Merger==
