Richard McCuistian grew up in Alabama learning from his father who ran an automotive repair shop. Richard has worked for nearly 50 years in the automotive field as a professional technician, an instructor, a freelance automotive writer for Motor Age, ACtion magazine, Power Stroke Registry, and others (published every year since May 2000). He has developed training courses and written or edited training material for companies in the U.S. Canada, and the Netherlands, and even Bulgaria. He maintained an “ask a mechanic” website for 10 years answering questions emailed to him from all over the world.
Richard has an instructional automotive YouTube channel “McCuistian” with 13,500 subscribers and over 1,300 videos. Much of his professional work requires photography and videography in shop environments, but Richard also enjoys taking pictures of landscapes, skyscapes, old barns and houses, small towns. 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.
