Marriage Alive International, founded by David Arp, MSW (www.10greatdates.org), and his wife, Claudia, is a ground-breaking ministry dedicated to providing tools and training to empower churches to help develop stronger marriages. The Arps are the authors of the 10 Great Dates series and the Gold Medallion Award-winning The Second Half of Marriage, among other books and video courses. The Arps have made appearances on the Today Show, CBS This Morning, PBS, and Focus on the Family, among others. USA Today, the Washington Post, the New York Times, the Wall Street Journal, and Time magazine have all featured their work. You'll probably find them hiking trails in northern Virginia, where they live, or in the Austrian Alps, where they love to hike, when they're not writing or lecturing.
