True Riches: What Jesus Really Said About Money and Your Heart

John Cortines oversees the Maclellan Foundation’s investments and strategies to grow a global movement of generosity among all believers. John began his career as a Petroleum Engineer.  While at Harvard Business School, he encountered a radical call from God to reframe his perspective on generosity and ultimately shifted his career into the nonprofit sector. Prior to his present role, he spent five years helping lead the ministry of Generous Giving. John is coauthor of two books on biblical generosity, which together have over 50,000 copies in circulation. John and his lovely and gracious wife, Megan, have three biological children, as well as twin foster babies in their home. In addition to these five young humans, they also manage nineteen egg-laying hens. John holds an MBA, an MS in Geophysics, and BS in Chemical Engineering.
