Meet the Team

Dr Sam Davis, and his wife Rowena, reside in the south of Spain on their health farm called Unochenta. The name Unochenta means 180; uno for number one and ochento is 80. The name was chosen after Dr Sam experienced a 180 transition in his life. His health journey is a powerful testimony of God’s ability to “restore health unto thee” and healing of our wounds (Jeremiah 30:17). In the same way he would like others to experience wholistic health according to God health plan. Dr Sam has completed a professional doctoral programme in Original Medicine and is committed to the medical missionary work, recognising “that soon there will be no work done in ministerial lines but medical missionary work’ which is “the gospel of healing and blessing and strengthening.”(Counsels on Health, 533.1-2)
