The Catholic Diocese of Techiman was created on 28th December, 2007 by His Holiness, Pope Benedict XIV. It was curved out of Sunyani and Konongo-Mampong Dioceses. Most Rev. Dominic Yeboah Nyarko, the first Bishop of the Diocese, was ordained on March 29, 2008. The Diocese shares borders in the North and West by Damango Diocese in the Northern Region of Ghana, South by Sunyani Diocese and East by Konongo-Mampong and Kumasi Dioceses.
The Diocese lies within the transitional zone of Ghana, between the forest zone, in the south and the savanna, in the north. It covers an area of about 25,500 square kilometers, constituting 64.46% of the total surface area of the Brong-Ahafo Region of Ghana, majority of which are rural areas. 2015 statistics indicates that the diocese has a total population of Diocese 904,156 of which 78,330 are Catholics

For example, it has a high illiteracy rate of 60%, with less than 10% of the population attaining a post-basic education qualification. The doctor-population ratio and nurse–population ratio are about 1:50,000 and 1:3,000 respectively, compared to the national ratios of around 1:10,452 and 1:1,000. About 70% of the economically active population is involved in agriculture and related activities. Small-scale manufacturing activities involving the fabrication of farm implements, storage containers, donkey carts, etc., go on in Kintampo, while Techiman (19% of its workforce) leads in commercial activities. With respect to institutional sector employment, the private informal sector provides employment to about 86% of the workforce.
