David Arp, MSW, (www.10greatdates.org) and his wife, Claudia, are founders of Marriage Alive International, a ground-breaking ministry dedicated to providing resources and training to empower churches to help build better marriages. The Arps are authors of numerous books and video curricula, including the 10 Great Dates series and the Gold Medallion Award-winning The Second Half of Marriage. The Arps have appeared on the NBC Today Show, CBS This Morning, PBS, and Focus on the Family. Their work has been featured in publications such as USA Today, the Washington Post, New York Times, Wall Street Journal, and Time magazine. When they are not writing or speaking, you'll probably find them hiking trails in northern Virginia, where they live, or in the Austrian Alps, where they love to hike.
