About
Your DNA Guide is a specialized online education platform founded by Diahan Southard, designed to help everyday people understand and apply their DNA test results for genealogy and family history research. Whether you've already taken a DNA test or are still deciding which one to take, the platform offers structured pathways for every stage of the learning journey. The platform is built around a proprietary SPIN learning process: Study (expert instruction breaking down complex science into everyday language), Practice (guided activities with exercises and repetition), Implement (applying learning to your own DNA results), and Next Steps (personalized guidance based on your discoveries). This methodology ensures learners not only understand the theory but can take real, actionable steps. Course offerings cover a wide range of DNA topics including AncestryDNA, FamilyTreeDNA, Shared Matches, WATO (What Are The Odds), YDNA for Genealogy, Finding Living Relatives, DNA Skills Workshops, and Endogamy & DNA. Free educational resources are also available for beginners. Your DNA Guide is ideal for hobbyist genealogists, adoptees searching for biological family, and anyone curious about their heritage who wants to move beyond raw data and actually solve family mysteries. With more than 10,000 courses taught and hundreds of verified success stories, it is one of the most trusted DNA education resources available.
