John Cortines

John Cortines oversees the Maclellan Foundation’s global granting, working alongside a team that speaks 30+ languages and works in every corner of the globe.  He began his career as a Petroleum Engineer with Chevron, but while at Harvard Business School he encountered a radical call from God to reframe his perspective on generosity and move into the nonprofit sector, where he has held various leadership roles for the past 10 years.  John also serves on various boards, including that of UTG, Inc., a publicly traded life insurance company. 

John’s books include God and Money (2016), True Riches (2019), and Wisdom Over Wealth (2025), which together have over 90,000 copies in circulation. 

John lives in Tennessee with his lovely wife Megan and their six children, where they homeschool and homestead.  He holds a MBA, MS in Geophysics, and BS in Chemical Engineering.
