 Joyce A. Shelton, PhD
Professor of Biology
On faculty since 1988
Reflecting on her time at Trinity, Dr. Shelton says she is grateful to have been able to serve the Lord by doing work that she truly loves together with godly colleagues, whom she cares for and respects. "When I think of the countless students God brought, not just into my classroom but into my life, I am both amazed and humbled. I was privileged to teach and mentor them, to pray with them, to help them grow and mature in faith, in character and in their knowledge of God’s word and his world, and then, beyond graduation, to see them serving faithfully as Christ’s agents of grace and truth in so many places and ways. It was a precious gift. I will miss Trinity and I continue to pray that it flourishes. It is an all too rare oasis in our increasingly uncertain world: a safe and caring community wherein students can learn and discern God’s purpose for their lives." |
