After launching his career in the Texas oilfields, John Cortines has recently decided to advance the biblical message of generosity full-time, joining the leadership team of Generous Giving. Turning down a lucrative expatriate job to serve this mission has been the defining moment in his own generosity journey — a journey in which God has proven tremendously faithful. Previously, he worked for oil companies in several locations across Texas and Louisiana, most recently as a petroleum engineer for Chevron, where he conducted complex decision and financial analyses of deepwater oil and gas projects. He holds engineering degrees from Texas A&M University (BS, 2010) and KAU of Science and Technology (MS, 2011), and an MBA from Harvard Business School (2015). A native of Indianapolis, IN, Greg Baumer grew up attending Indiana Hoosier basketball games and working with his dad every Saturday in the family business. He went on to earn his BS in finance, business economics, and public policy from Indiana University in 2008. Greg began his career with McKinsey & Company, serving clients in a wide range of industries including manufacturing, retail, and healthcare. He then worked as an investment professional for the private equity firm Advent International, where he focused on investments in the healthcare sector. After earning his MBA from Harvard Business School in 2015, Greg joined Nashville-based healthcare technology startup naviHealth as vice president of product development and innovation. It was while taking a Harvard Divinity School course called God & Money that Greg began to think deeply about the intersection of faith and finance.
