Gayle Jordan

Gayle is a former Southern Baptist who left the faith 10 years ago when her then-teenagers began asking questions she could not answer. Her research led her (and her children) into the light of reason and rationality. Years later, she still feels the effects, both positive and negative, of that dramatic shift in perspective and attitude. It is this sympathy and compassion that drives her to reach out to help others navigate the emotional and physical process involved in leaving one’s faith.

Gayle is an attorney and former personal trainer. She lives on Freethought Farm in middle Tennessee, where she spends her days amongst her longhorns, goats, donkeys, chickens, and dogs. She blogs about life on the farm, endurance event training, and secularism at Happy. Healthy. Heathen.
