About
Dr. Rahul Iyengar is a board-trained primary care physician and the founder and CEO of Members Health Co, a Nashville-based, membership-driven primary care practice rethinking how healthcare should be delivered. After more than a decade of rigorous medical training, Dr. Iyengar became increasingly frustrated with a healthcare system that prioritizes treating symptoms over preventing them. This experience inspired him to create a model that places deep emphasis on preventive medicine, meaningful doctor-patient relationships, and personalized health strategies rooted in advanced biomarker testing and proactive planning.
Dr. Iyengar’s philosophy centers on catching health issues long before symptoms arise, using comprehensive bloodwork and advanced testing to uncover imbalances in hormones, inflammation, nutrient levels, and other key biomarkers. He believes that prioritizing preventive care not only leads to better health outcomes but also saves patients substantial cost and time over the long run.
