Founder of Your DNA Guide

Diahan Southard

Diahan Southard has been helping people use DNA to explore their roots for over 20 years. She started her career at the Sorenson Molecular Genealogy Foundation, which created the DNA database that became AncestryDNA. After witnessing the power of DNA for family history–and the difficulties people face in using it effectively–she launched a pioneering career in DNA education.

Over the last 20 years Diahan has given hundreds of lectures on DNA from Burbank to Oslo, London to Seattle, to crowds of tens to thousands. Diahan’s talents for making DNA accessible, exciting and relevant are on full display as host of the PBS special, Your DNA Secrets Revealed. Diahan teaches on global platforms such as RootsTech, GenealogyTV and Legacy Tree Webinars. She appears on popular genealogy podcasts and is a DNA columnist for Family Tree Magazine.
