Tap and Denise Hornor got married in 1978 and have three sons and eleven grandchildren. They have been actively involved in ministry since 1996 under MGM International, dedicating their lives to planting churches and spreading the Gospel in Sinaloa, Mexico. In 1997, Tap founded Iglesia Bautista Betel in Alhuey, Sinaloa, where he served as pastor until 2018. After that, he served as interim pastor at Iglesia Bautista Horeb in Navolato until 2022.
