Angel Castillo, born circa 1960, died N/A, is a Dominican preacher and church planter whose nearly four-decade ministry has focused on serving the poorest communities of Santo Domingo through Iglesia Fundamento Bíblico and beyond. Likely born in the Dominican Republic, Castillo—affectionately called “Angelito” by friends—founded his church in one of the capital’s most impoverished districts around 1995, after coming to faith and training in ministry. His preaching, rooted in biblical fundamentals, emphasizes the gospel’s power to transform lives, delivered with a warmth that resonates in a nation marked by economic disparity. Alongside his wife, Clara, he has built a family-oriented ministry, with sons Ariel and Daniel active in church and community work. Castillo’s ministry extends beyond preaching to practical outreach, including planting multiple churches over 20 years with pastors he mentored, and leading mercy efforts like food distribution through Children’s Hunger Fund and annual Christmas dinners for 500 children. His response to the 2010 Haiti earthquake—rescuing orphans and sustaining their care—highlights his hands-on approach, as does his oversight of Vacation Bible Schools drawing hundreds.
