He has produced a coffee table book of digital watercolors called “Memories of South Alabama” created from his personal photos, along with a dozen Christian fiction short original novels and a collection of short stories, all available in Kindle or softcover format. Richard has written a 2,500-word Bible study every week for the past 20 years and uses it to teach a small group at his church every Sunday morning.
