Marriage IQ is led by the husband-and-wife duo of Dr. Scott Hastings, a medical doctor, and Dr. Heidi Hastings, a dedicated marriage and sex researcher. Together, they bridge the gap between clinical medicine and relationship psychology to provide actionable health and wellness advice. The team specializes in destigmatizing complex topics through evidence-based series such as the Save Marriage Challenge and their deep-dive 13 Secrets curriculum. Their work frequently addresses high-friction areas including erectile dysfunction, the neurobiology of anger, and the impact of parental grief on domestic unity. By combining medical insights on sexual wellness with Gottman-influenced psychological frameworks, they offer a professional resource for couples navigating intimacy hurdles. A recent focus includes their analysis on the Respect Gap, which utilizes brain science to explain relationship conflict. This medical-meets-relational approach provides a high-trust environment for exploring sensitive health topics that often go unaddressed in traditional wellness spaces.
