Isaac responded to the call of ministry in Mexico. In 2002, he and his family relocated to South Georgia, where he attended Asbury Theological Seminary. Two years later, in 2004, they moved to Lake Park, where Isaac served as Associate Pastor for Hispanic Ministries. In late 2015, he transitioned to lead pastor at Lake Park UMC. In 2019, Isaac and his family moved to Waynesboro FUMC, where they continued their ministry. Since July 2023, Isaac has been serving as the pastor of Trinity Methodist Church, a Global Methodist Congregation, and is excited to see God at work in Trinity and the Waycross community.
