Pastors Maher and Sarah Castan are the founders of OLA World, church planters, pastors to pastors, and global ministry leaders with more than 20 years of experience serving across diverse cultures and ministry contexts.
Both were raised in missionary environments. Maher grew up in Puebla, Mexico, near the mountains of Oaxaca, where his father has served as a missionary for more than 40 years, planting churches and reaching remote communities. Sarah grew up in a missionary family serving in Managua, Nicaragua, in the years following the country's civil war.
Together, their ministry is rooted in the United States and Mexico, reaching the nations with the heart of pastors, the feet of missionaries, and the hands of executive leaders and administrators—developing leaders, coaching pastors, building teams, strengthening churches, and leading outreach and missions initiatives.
As bilingual communicators, Maher and Sarah preach together in English and Spanish, connecting with multicultural and multigenerational communities.
Today, they continue serving in pastoral leadership in the local church alongside their daughters, Alessandra and Mila, while carrying a shared passion to mobilize people to live on mission—locally and globally.
