Kelly Hart – Director of Harvest Kids

Born: Cedar Rapids, Iowa
Married to: Nate
Contact: khart@harveststlouis.org

Kelly grew up in a Christian home and took personal ownership of her faith as a college freshman at Truman State University. Aiming to become a math teacher, God changed her plans when she met the love of her life, Nate, and they decided to teach about the love of Jesus together. After getting married, eighteen years ago, they both attended Central Christian College, where she earned her Associate of Arts. Since becoming members at Harvest in February 2017, Kelly has been serving alongside her husband in Harvest Student Ministry. As a mom of five beautiful daughters, Kelly definitely has a passion for teaching children and helping them to grow in Christ. One of her favorite verses is 3 John 1:4: "I have no greater joy than to hear that my children are walking in the truth." This joy extends to the ministry and all the precious kids God has entrusted to her care.
