TANIA HILTON

Unite Leadership Director of Engagement Development

Affiliating herself with the church for the first time in 2015, Tania would consider herself a “New Believer.” Yet, her mentors immediately saw her leadership potential and passion for Christ. In 2019, Tania was asked to join the ULC team, bringing her IT skills and adaptive self-starter skills to take on many different roles before settling into her role as Director. She has a BA in Christian Thought & Practice and is happily married since 2007 with three kiddos ages 15 - 11 who keep her on her toes. Currently pursuing her Master's in Divinity, Tania aims to help individuals identify areas of spiritual, personal, and vocational challenges where they might feel stuck, guiding them through the transformative power of God's Word and promises through Biblical Counseling.
