Dr. Laffey was in practice for six years with Saint Louis University and served as an Associate Professor of Medicine and concierge physician prior to opening Thinnergy Medical Weight Loss. She has extensive experience in all aspects of family medicine including obstetrics/gynecology, pediatrics, geriatrics, HIV/AIDS care, and emergency medicine.

Her team-oriented, multi-modality approach supports patients at any point in their weight loss journey.
